FYI, this is more of a log for my use. But read if you’re interested.
The original TopTwit has pretty much failed for the time being, but that doesn’t mean the idea is dead. Soon I’ll head back into that code and clean it up (a year later). It does still work if you want to try it out– sign up and build your twit lists and you have a nice page to keep track of your favorites.
On the other side of things, I’ve been having fun playing copycat to the 40 most recent links from @davewiner. You can see my version over at 40 most recent links from @jeremyfelt. I’ve recently added support for bit.ly and post.ly in addition to the default tr.im functions. I have categories built in (using hash tags), but I took them off of the display for now because it seemed like a waste of characters. Not sure what new features will show up here in the near future, but it definitely needs a design overhaul.
