This blog started out called the unblog back when blog was a new-ish term and I thought it was silly. I'd been on mailing lists like fork and Kragan Sitaker's tol for years and couldn't see a difference between those and blogs. I set up some mailing list archive software to look like a blog and called it a day.
Years later that platform was aging, and wikis were still a new and exciting concept, so I built a blog around a wiki. The ease of online editing was nice, though readers never took to wiki-as-comments like I hoped. It worked well enough for a good many years, but I kept having a hard time finding my own posts in Google. Various SEO-blocking strategies Google employs that I hope never to have to understand were pushing my entries below total crap.
