BlogString.com, in its current incarnation, covers startups, social media, PR, and anything its authors feel is interesting.

Started by Nathan Burke in April 2007, the blog mainly covered beta versions of web apps, with some social media and startup monetization discussions thrown in. In June, Sarah Wurrey joined BlogString, and brought a new perspective to a random, narrowly focused blog. With the addition of Sarah, the blog now incorporates humor, PR, and social networking from a non-geek perspective, which is nice.
