How do you use Asana for bug-tracking? We're considering doing so too (We already use Asana for task management, etc), and would love some pointers from someone who's already done so.
They have a guide (http://asana.com/guide/videos/bug-tracking) in their help pages about it. I use it too, but not their way. I don’t have a “Bugs” project. I have a “Bug” tag that set to bugs in different projects. If you already have a projects structure that works for you and can hold issues like bugs, this might work better.
We use asana as a bug-tracker at https://circleci.com. Its pretty good, and doesn't get in your way, but we can't really integrate it into our workflow. They don't have Hipchat integration, and their API isn't full enough to set it up ourselves with Zapier.Their support also isn't very good, they replied to the problem with basically "dont care".
