Almost always return an interface type and return the most generic one making sense for the typical consuming code.

You never know what an interface type is hiding.

I'd disagree and say: Always return conrete Types but only accept interfaces (where appropriate, eg. public methods). This way you don't limit your users but still manage to have lose coupling.

Don't always blindly return interfaces instead of concrete types. Understand the difference and the implications, then choose depending on your requirements.
