All points are valid advice. Thanks for your feedback. In the long run it may become a platform but I would like it to be small and private, so users don't feel like they are the product. Privacy and security are paramount and won't be traded for anything. Total encryption could be a feature. Backups and data portability from the get go. The whole idea is to make a thousand people happy without compromising their trust in the service. If I decide to go on I'll start building a framework to make modules plug and play, then dedicate time to each, one by one.
