Scary. Very, very scary message.
At the moment it looks very v0.1 though. I'll wait for the release version.
'Raise a bug' ->
http://www.bitbucketcards.com/samtardif/bitbucket-wallboard
-> 'Error: Couldn't find that repository.'
* (Of course, if Fog Creek hosted git repos I never would have been a BB user in the first place..)
We've built https://www.blossom.io for exactly that reason. But there are many tools out there that use this visualization or a hybrid of lists and cards, so from my POV definitely not a rip-off, just a natural evolution over the last few years.
This looks like exactly what is needed. I think I'm being cemented in as a serious BitBucket advocate.
One `usability` thing: it will be good for example to have a button in Bitbucket which will open Cards in new tab in for a given project.
