In my view this looks like a great tool for agile workflow. A replacement for the board with sticky notes. regarding the scale ... most if not all bug-trackers become a junk yard of bug reports. thousands of them. most never get fixed. lots never get looked at. This tool lets you store things that you are going to do in the near future. And the rest... lets deal with it when we get there. I think if you can't remember it a month from now, it probably not important. In any real project you can never deal with all the bugs and reports. so you usually deal with the most serious ones and the ones that get reported most often. the important ones go on todo right away, and the often reported ones do not need another place for them. people will keep reporting until you deal ;) so this tool is effectively lets you plan your activities in the short and medium term. once you get to the 'next year' you will have other priorities and new things to do. there is no need to plan it now. Im definitely going to try it. Currently we mostly work with Pivotal Tracker and also trying out Trajectory from Thoughtbot. It looks like Trello might be a decent contender in the space.
