Postgres is a better fit for most Ruby web applications. When you first launch your app, you'll have a tiny handful of users and won't have any problems fitting it in a free Heroku instance on the free 5MB shared Postgres, and the compromises you'd have to make with your data model to fit a database like Riak aren't going to pay off until you get enormous. Postgres and ActiveRecord get the job done quickly and without fuss, and allow you to launch quickly and see how your app is received.

RiakCS looks interesting, is it/will it be open source?

[justinsheehy]

RiakCS is not open source right now.

Parts of it may well be open sourced over time.

He is right in that you don't hear much about Riak success stories, even though from the word on the street it's a good product. Perhaps this is something you guys could focus on putting together?

[pharkmillups]

Absolutely. We are working on making users stories more visible.
