Don't think that was us... Stack hasn't been around that long. But in any case, Trello can certainly be used by dev teams, but it's becoming increasingly clear that dev teams are not their target audience. They're selling to artists, film-makers, students and musicians! (This is from their own landing page btw). We think there's a lot to like about Trello, we just want to deliver a better product to better suits the intended audience. See other comments for the sorts of features that we (and other devs) feel are important.
