What a week for Mashable! We recently launched Follow, our social layer to help you create a profile and find and share stories to the public. Despite the good news close to home, this week was also a tough one for the journalism community with the death of two top photojournalists, Tim Hetherington and Chris Hondros, who were hit by an rocket-propelled grenade while working in Libya.

Despite the ups and downs, the good folks at Mashable have come up with another batch of tools and resources to help you follow whatever news and topics interest you. This week we have stories about Obama’s visit to Facebook, the evolution of web design, PR pro tips for YouTube, and eight ways to improve live events using social media.

Looking for even more social media resources? This guide appears every weekend, and you can check out all the lists-gone-by here any time.
