This is the first time I've looked at our app since we sent it in (that I can recall), and I was extremely surprised about how prescient we were on some things. Not only Google Calendar, but who would be potential acquirers (we were talking to them during Kiko and actually had a verbal offer that fell through, although that is a different story to tell), that social networking features would be important in all web applications, that javascript client applications would be actually a good thing to do.
The only thing we weren't good a predicting was our release schedule :)
