That is great, but it doesn't work well for teams. Paper also attracts coffee stains, so you tend to write a new list every other day. Gets tedious quickly.

I really think a good software solution is the way to go. (Disclaimer: my startup is working on one)

Hint: I prefer a real desktop app for this sort of thing. If there were a cross-platform app with a decent interface that we could use for managing team to-dos I'd be in love. :-)
