Tina3 got some updates a while ago. It now tracks activity in the IRC channels it's on, though I still have to add support for some things. In addition, it now also tracks line counts... though it also penalizes those who think they can spam their way into the top :)
As for MiniSM: not really that much. Recently, all of Hiryuu's simfiles were parsed, though they won't last long there (only temporary). More importantly, a pretty nasty bug was fixed involving UTF-8 byte order marking in text files; this would give no title for some simfiles, and has been partially fixed. Though a better idea would be to just rewrite the entire thing from the ground up (and is, in fact, something to do later)...
...
As for Shitburst, that would be a joke page I'm making to basically poke fun at the whole Web 2.0 idea. I loathe the idea of gradients everywhere, shiny buttons and shit, and all of that other crap. Especially starbursts. I don't expect it to go anywhere other than being a joke page there (and it won't ever be finished either, by design).
Anyway, the MiniSM update was required to prepare stuff for the other simfile-related website I'm half-working on. More details on that as the idea develops, though considering how long it's been since I decided to start working on it...
