An article I wrote a couple of months ago for PyZine just got posted. Getting Twisted. It has a high-level overview of Twisted and discussion of simple protocol implementation. It's the first in a series, the rest of which will only be available to paid subscribers. To become one, hit this here thing.
I did some work on Infogreater over the weekend, fixing a bunch of really annoying UI bugs -- mostly to do with the window not following your selection. IG is now that much closer to Freemind, but it's still not as complete as freemind nor does it offer any features that freemind doesn't have.
However, I just began work on a new kind of node that saves itself and all children as a simple text file with a nested list. I plan on using it for TODO files in my various small projects. Hopefully next weekend I will get this and even maybe one or two other small ideas implemented and have another release out.
Anyway, if you're interested, go grab Infogreater.
