That's a question every startup should ask (before it starts): What is my business about? Help ('real' utility) or entertainment. The answer more and more defines business model. You can charge users for help, but can you (really) charge them for entertainment? They are going to expect more to be free. If music is expected to be free (last.fm, P2P) soon film will follow (Hulu) and other, currently considered must-pay-for timekillers. The biggest mistake is to think that you are in one group while having business model for the other. Exceptions do exits, I'm aware of that. - Marcin Grodzicki from FriendFeed MT Plugin
