What are some worthy open source projects to contribute to?
(besides Masto obvi)
@hauntedlatte depends on what you want. I spend most of my time working on GNUnet. It's not just regular developer work, we also have a big rewrite of the documentation (Texinfo) going on, work on a new website in Django and more languages than just C.
We definitely have too few people all the time, and haven't had the chance to work full-time on this for a while.
