The dev blog entry was definitely one of the best I've read in a while on lessons learnt from a project. This line in particular,

The main idea was: “Stop worrying about if there’s something better. If you can do it right now then just go with that.”.

Says it all. That's a difficult wall to break past and I've struggled and I'm still struggling with it for my Android app. And I don't even have an app review to pass.... shame on me for not having any app out there. Thanks a lot for sharing this. The dev article was definitely an inspiration. Ah well. Good luck with the future run of this. You are right. This database does have a huge amount of potential in it so it'll be interesting to see where this goes :).
