Twitter has a huge green community. There are green media, green companies, and green charities all active on the microblogging service, as well as a whole bunch of individual environmentalists and green bloggers. The #EcoMonday hashtag — the environmental equivalent of #FollowFriday, in which Twitter users suggest “green” tweeters to follow and share green news and info — has grown into a regular trending topic every Monday, along with a variety of other green initiatives.
Below are more than 75 environmentalists, conservationists, green-living enthusiasts, eco experts, and green organizations that offer up some excellent eco information on Twitter. We’ve broken the list up into two categories, people and organizations/publications. Please leave other great green Twitter users that deserve a follow in the comments, because we couldn’t possibly list them all.
The first part of our list is focused on individual people whose tweets are mostly related to environmental issues like sustainability, conservation, green living, alternative energy, and climate change. Our list touches just a small number of the essential Twitter users anyone interested in the environment should follow.

What can you use the application for?
Zocdoc.com is an online service which allows patients to book doctor and dentist appointments. Doctors and dentists can be searched by specialty, location and type of insurance that they accept. Patients can read reviews of doctors and dentists written by other patients. The service allows patients to search for the following specialties: Allergist, Dentist, Dermatologist, ENT, Ophthalmologist, OBGYN, Orthopedic Surgeon, Primary Care Doctor and Psychiatrist.
The site currently lists doctors and dentists located in the Brooklyn, NY and New York, NY areas, but plans to expand to other locations and specialties over time.
To use the service, patients select a specialty, type in a location (city and state or zip code), and optionally select their insurance company and plan. The site returns a list of doctors that match their criteria, with available appointment times shown. The site also shows a map with the location of each doctor pointed out on the map. Patients choose a date and time with the doctor of their choice, select a reason for the visit, and the appointment is booked. Patients can view a complete profile of each doctor and read their reviews before selecting them. The profile includes information about the doctor’s education and experience.
What is the history and popularity of the application?
New York-based Zocdoc.com was launched in September 2007 by Cyrus Massoumi (currently CEO), Oliver Kharraz (currently COO) and Nick Ganju (currently CTO). The site has grown steadily since launch, adding new specialties and locations covered. The site currently has tens of thousands of unique monthly visitors, and has an Alexa page rank well below 150,000.
What are the differences to other applications?
Competition to Zocdoc comes from sites such as the WebMD Physician directory and AMA Physician Select. There are also many other physician and dentist directories on the web. Most of these have a much larger area of coverage than Zocdoc, with WebMD and the AMA site being national. However, they do not allow you to book an appointment – this feature is unique to Zocdoc. The Zocdoc service should prosper as it expands to other areas, as the concept has worked well in the areas currently covered.
How does the application look and feel to use?
The Zocdoc site has a very clean and uncluttered look and feel. Searches return results very quickly, and page loads are very fast. The site is very responsive overall. Navigation is intuitive, and there is a convenient search dialogue located on the home page of the site. The site also includes directories organized by name, practice, location, specialty, condition, insurance and language.
How does the registration process work?
Registration at the Zocdoc site is not required to search for a doctor or dentist, but is required to book an appointment. The registration process asks for first and last name, zip code, gender, date of birth, email address and password. In addition, the site sends a confirmation code via telephone or SMS text message which must be entered to complete the registration process.
What does it cost to use the application?
Users don’t need to pay to use the application, there is no premium membership to the Zocdoc site offered.
Who would you recommend the application to?
Zocdoc is recommended to anyone in the Brooklyn or New York area who needs to schedule a visit with a doctor or dentist. It is especially helpful if the user needs an appointment quickly. The reviews of doctors and dentists that have been written by other patients are also very helpful. The site is also recommended to doctors who would like to increase their exposure. Hopefully the site will complete the planned expansion into other areas and specialties soon, as there is a need for the service nationwide.

15 Jun 2009A variety of multiclient instant-messaging services have cropped up that allow users to communicate with each other over the Web. Some can be downloaded onto your desktop, while others can be accessed on the Internet. In either case, they’re worth trying out, if you want to enjoy a fine experience communicating with your friends.
Adium Adium is my favorite multiclient instant-messaging tool for a few reasons. It supports practically any IM platform around, including AIM, Yahoo Messenger, Facebook, MySpace, Google Talk (via Jabber), and more. It even has a plug-in for Skype.
You’ll rarely have any trouble communicating with friends in the service. But its most redeeming quality is that it’s open source. So, if you want to modify the code to fit your own IM desires, that’s possible. And those in the open-source community are constantly improving the product, whose updates typically install with ease.
When you download Adium (it’s available for Mac OS X), you’ll have the option of choosing your IM service. By default, Adium takes on the same design as Mac OS X. But with the help of some plug-ins from Adium’s site, called “Xtras,” you can customize it as you see fit. Those add-ons include emoticons, dock icons, scripts, and more. I could go on about Adium, but I think that you get the point: if you’re a Mac OS X user, it’s worth trying out.
Adium takes on the look of Mac OS X by default.

Digsby Digsby is a multifaceted tool that lets you communicate with friends over instant messaging, e-mail, or social networks. I recently took a look at its social-networking capabilities. After having the opportunity to use its IM services, I was just as impressed.
After installing Digsby on my Windows PC (Mac and Linux versions are reportedly on the way), I was able to log in to my accounts on AIM, Yahoo Mail, Facebook, and others. Digsby’s app is designed well, with a more attractive interface than Adium’s default skin. Digsby also gives you the option of sending an SMS text message from the application. Overall, I liked Digsby.
Digsby lets you chat with anyone at any time.

eBuddy eBuddy is a Web-based multiclient instant-messaging app through which you can connect to AIM, Yahoo IM, MSN, Facebook, ICQ, and MySpace. Although it provides a bunch of options, eBuddy doesn’t quite stand up to the competition. It’s not as responsive as some of the other apps in this roundup, and I was unimpressed by its design. That said, I did like that I could view my Facebook friends’ profiles by clicking on a link in the client. I also liked that the app opens in a separate window–I find it more convenient than switching to a tab. Plus, it’s available for Android-based phones, as well as the Nintendo DS and Sony PSP.
eBuddy isn't the best-looking service, but it still works well.

Meebo Like eBuddy, Meebo is a Web-based instant-messaging tool that lets you communicate with friends on AIM, MySpace, Yahoo, and MSN. You can also chat with Facebook and Google Talk friends.
When you go to the Meebo home page, you have the option of inputting your credentials for any of those services. The instant messaging on Meebo is outstanding. It’s the same interface for all the sites, but you can get buddies’ contact information, see their Facebook status, and even check out their entire Facebook profile by clicking on the appropriate link, which opens the profile in another tab. Meebo is one of the more popular multiclient IM tools on the Web for good reason–it’s simple, responsive, and boasts support for a variety of clients. Even better, you can use it on your iPhone.

Pidgin Similar to Adium, Pidgin is an open-source IM client that allows you to modify it as you wish. If you don’t want to do that, you’ll still be satisfied with the software.
Once installed, Pidgin gives you the option of signing into your various IM accounts. You can chat with friends on AIM, Google Talk, ICQ, MySpace, and others at the same time. It’s not as good-looking as some of its competitors, but it’s designed more for the power user who wants to be able to chat with as many people at a time as possible. Pidgin is ideally suited for Windows machines, so that may be a problem for some. If you want to use an open-source instant-messaging platform on a Mac, Adium is your best bet.
Pidgin asks you to create accounts when you first start it up.

Trillian Trillian is a desktop IM client that supports instant messaging on AIM, ICQ, MSN, Yahoo Messenger, and Internet Relay Chat. Unfortunately, it’s available only to Windows users at this time. The company is promising Mac and iPhone support in its follow-up version of the software, called Trillian Astra.
Overall, I was really impressed by Trillian. It supports the standard features like group chat, audio chat, and the option to view profiles. But having the ability to change skins was quite appealing. I was able to customize the experience to match my tastes. From dark to bright, there’s at least one skin for everyone. Trillian is, quite simply, the most beautiful multiclient IM service in this roundup. If you want more functionality (such as bringing in your Google Talk contacts), you can also buy Trillian Pro, which costs $25.
Trillian Astra is coming to Trillian.

2. Trillian: Beauty matters, and Trillian delivers.
3. Meebo: The best Web-based multiclient IM app.
