I went Thursday and Friday because a free ticket fell in my lap and I was able to stay with my sister.  In my experience it wasn't about stats or clothing and I met plenty of writers of small blogs who don't run advertisements.  I also got to hang with some major bloggers that I'm totally fan girl about and buy the books (and get them signed) of authors I wanted to support.  I left early because I'm SO pregnant and the venue was SO large and frankly the thrust of the conference is marketing yourself and that's not my bag at this time.  I did get some flashes of inspiration while I was there and that's pretty much what I was hoping for.  I doubt I will go again because I am a hobbyist and have a full time career, but now I know what I'm missing and I won't feel bad about missing it.
