Ask HN: What project management / ticketing app do you use?

I've used Bugzilla, Mantis and Jira.

Jira, while not free, is the best of those three for sure. They have a nice $10 for 10 user license that is quite affordable and besides the 10 user limit, has no functional limitations.

I've read good things about FogBugz but have not used it myself.

@joncrawford has been compiling this list based on his needs: http://t.co/6LSV0j5

Bugzilla[1] and Icescrum[2].
