On Hacker News, uuilly tells how they implemented a simple bugtracking scheme using DropBox, see
Using Dropbox to Track Bugs. I don't know if I should smile because this is a nice example of how to find a simple and pragmatic solution to some problem you have. Or if I should cry over all the bugs they are now going to track instead of fixing them, see
Why Bugs should not be Tracked.
