Chandler seems to have been coming along fairly slowly for a while. I’m not sure how exciting this is but could be the beginning of something interesting.
The Chandler team have been building up some Python infrastructure, grappled with various technologies, and rejected the ones which have turned out to be too much trouble to work with.
Maybe they have some nice components?
Now they’ve done a sensible thing and focused on one application : shared calendaring, which they hope will get them some users and attention (the most useful resources). After that, they can expand to other applications.
OTOH, calendaring doesn’t interest me much.
