These would have been the subjects of my posts on May 5, 2007, if I just had the time:

• Social Media Releases - Everything You Ever Wanted to (or Should) Know - Brian Solis has put together a kind of enciclopedia of the Social Media Release, with a lot of links to the articles and posts that have marked the conversation so far.
• If the Shoe Fits… Social Media in Seven Boxes - Kami Huyse has social media organized in seven categories. Very interesting sistematization, worth at least a second thought by those PR that still refuse to understand that today stakeholders are quite different from yesterday stakeholders.
