Great concept for an app, but I just tried using it to sync my bookmarks across two different computers - and it didn't SYNC, it OVERWROTE. When I synced the second computer, I expected to end up with a combination of the bookmarks that had been on both computers. Instead, the second computer's bookmarks became an identical copy of the first computer's bookmarks, and the bookmarks I used to have on the second computer were gone. I had no warning that this was going to happen.
