I added tags to all of my posts and curated them into alphabetically organized sub-blogs that you can individually access through the top-right “blogs” menu. I also redid the menu’s CSS and I think it looks much nicer now. There’s a particular thing about it that bothers me, but I like it more overall.
Some time ago I also turned my about page into a personal wiki for easy organization and whatnot, and I recently set up a microblog too, which I call “μCHK” to keep with the micro theme. I didn’t add it to the site menu, though, because, honestly, I don’t think it serves much of a purpose with Twitter being more or less the same thing.
