A rather small number of people are working on it, but it's chugging along. Kenton has the keys still so he does basic vital things. A few new apps are in the pipeline. I'm still rather interested, and am developing another app that I expect to get a lot of attention when it's done.

There's a fund:

The bigger it gets, the more time can be diverted toward it. I was recently paid to upgrade the Etherpad app. But in theory it could go toward core development (which wouldn't be me).
