Phone support is a hard thing to do well. And we have a pretty high bar for support. So I know this sounds like a dodge, but we really are waiting until we can confidently roll out strong phone support to push it.

For now, whenever a customer has a problem that can't be solved via email, one of the founders will call.

Obviously that doesn't scale, so we need to figure out phone support, but we're aiming for what I call "Zappos-level" quality and that's easier said than done.
