Ben Werdmuller put together a nice site laying out current tools for blogging, and why you might want to start. If you wanted a good summary of the state of things and what to try, it’s a good site to check out!
Not much to add in, other than that I agree, it’s nice to do and it’d be swell to see more folks blogging again. Do you run a blog? Let me know, I’d love to add it to my rss feeds!
