Sadly, the service might shut down before the end of 2015 because of time/money problems [3].

It's fair to tell me "then why don't you contribute / do something instead of complaining?", but as much as I'd like to, it's got lots of moving parts and needs significant time and lots of different skills, or some form of backing to pay for those. Even if it can be turned into a solid business, it will still require resources to support - not just the technology, but marketing etc. So far, I haven't seen anybody picking this up, but I really hope someone will. It will be a great loss to see it die.
