I so wanted to love it. I even build small automation tools around it. What destroyed it for me was the overly complicated taskserver, which then only communicated in it's own protocol (so I could sync tasks between different unixes, and apps following that exact format), but not in the much more widespread CalDAV format (which would have made it useful beyond the hobbyist scene).

Yes, I know, I could have developed it myself. But ultimately, that was too nontrivial to just throw it together, and I finally gave up.

I'm with JIRA now. It does what it needs to do reasonably well, without causing too much headaches.
