And to be honest, it's a process tool. Dealing with processes is boring.
Jira is better than bugzilla and trac. And much better than some tools, constructed from manure, from big IT companies and sold for very high price tags.
It's sad to me that they lost momentum. I think they got stuck trying to overcome tech debt and bug fixes and feature requests started to pile up.
From time to time I keep an eye on CommonMark implementations and fantasize about writing an MVP to replicate parts of Trac by composing existing tools. Unfortunately there are like 5 other things I'd rather do with my free time.
