Wow, this is incredible.

I'd love to know the following things:

1) Did you just "build it and hope they will come" because it looks like a lot of work?

2) How many of you worked on it and how long did it take you; the finish seems very high (with a few very small weirdnesses - e.g. it stopped allowing me to add new items to a checklist for some reason until I reloaded, in safari the tab crashes when switching from Kanabn view to List view).

3) What's it built in, backend and frontend wise?

4) Do you have funding?

5) I've always wanted Trello to allow me stacked lists within one column for various things (like mental models -> http://rosenfeldmedia.com/books/mental-models/), probably low on your list but for me it would be exceptional.

Thanks!
