BizBlogDirectory
I agree with Rick, this could become very big very fast. I've listed myself for two reasons, a) I'd like to expand my readership and b) I thought it was about time I tried out a wiki-powered page. Two birds with one stone! The directory looks very interesting. I'm sure there is some chaff in there, but I am going to go back and peruse the listing for interesting sites. I saw a few interesting ones on my first pass through.
Todd S. has taken another approach to a directory on business blogs (which, in some sense, my site already is): he has created an alphabetized wiki. (“What's a wiki?” you ask? It's basically a blog that any reader can edit or contribute to. Here's another definition, or just check out Todd's site and you'll get the idea.)
Definitely a different animal than my site, as all entries here have my subjective spin, plus categorization, while the BizBlogDirectory features descriptions by the site managers. My guess is it will get big fast. Something certainly to keep an eye on, and also a good place to register your blog, if you haven't done so already.
