It could be argued that Trello will eventually be larger than either of these products, so I don't think the story has been completely told. I've used Jira as a manager in both a large and a small installation and hated it both times. It feels like 90s bug tracking system with huge forms and intractable workflows.
With that said, Spolsky (although I think a lot of his writing is fantastic) rarely addresses his mistakes.
Agreed. I kind of don't get Trello. Always thought of it as kind of a lightweight "stack of cards" analogue best used for simple high-level planning along the lines of a Kanban board. Is that how people use it?
We used it recently as a kanbanish/scrumish board for a recent development cycle and it worked out pretty well. We had separate boards for each sprint, and a backlog board that contained some broad-swipe categories. It would definitely be nice if it had better integrations with fogbugz (which our team also uses) or other bug tracking platforms, but I imagine it would be challenging to do that and maintain its extreme ease of use/simplicity.
