title: Agile issue and feature tracker software
body: <p>I'm looking for the "best" agile-friendly feature and defect tracking software.  Currently, we are using fogbugz, but this is not terribly useful for teams following an agile methodology as far as I can tell.  There are better tools for this, such as Greenhopper for JIRA.  I've used JIRA before, but I'm wondering if there are any other tools that are better.</p>
