Good luck to him. He sounds like a good choice. So glad they didn't find some square-jawed empty suit. The fact that he heavily participates in online communities is a very good sign.

I do hope he has a delicate touch though. It's surprisingly easy to set off communities if you come in guns blazing. It would not be difficult to replicate the The Great Digg Rebelling of 2010.

Probably the best thing to do would be to win over the community by making very small and uncontroversial improvements. Nothing that is self-serving. UI improvements, better search, nicer notifications, etc.

Increasing revenue would be easy to do but very risky if it involves any new forms of advertising. I hope they can push that one off a bit or come up with something users don't find objectionable (which will be tough).

Reddit has grown so large with only very minor improvements over the years. It would be a shame to have someone "fix" what ain't broke.
