The random hammer of chaos came down a few more times, and I'm ready to declare November over. submoinmoin is pretty much done except for merge and any kind of performance; nagaina is still at 0.05, readme-blog gained a few features, and a conkeror-selection-unscraper pretty much works. So at least for me the whole "stay focussed on doing actual code" aspect of codemonth worked.
If it worked for anyone else, feel free to follow up with a mention. Likewise if anyone wants to try again for IAP, otherwise it's next November and a little more planning, in 2007.
(Also, I've seen no mention of a 2007 codecon, which I sometimes propose as another codemonth motivator; anyone have details?)
