Rex Hammock has a great post that explains why he blogs. It demonstrates that many blogs often are not confined to finite boxes the way media is. Someone can blog about their cat having a hairball and in the next post come up with an idea that solves global warming. Fred Wilson's blog seems to cover everything.
This could be the start of a valuable meme. What if we all did short FAQ posts like this one and tagged them? Then they can be archived and it would take on new value. It would help the PR community better target our approach while also making it easy for birds of a feather to flock together. Then again, there are already some services that do this like MyBlogLog.
I also like how Rex traces his lineage back to Dave Winer. I am part of the same tree. Robert Scoble, who Dave mentored, really gave my blog a boost when he granted me this interview back when I started three years ago. The whole blog tree is eerily similar to the famous Bill Parcells and Bill Walsh coaching trees.
