What this means for us?
This can be both good and bad thing.
The bad thing is, if you have even remotely successful fan page, people will send tons of messages to you.
The good thing is that now you can find fan pages that have a similar topic, and offer cooperation to the administrator.
Another good thing is, if you have a successful fan page, you do not need to leave your email in the updates any more, you don't have offer people to advertise on your fan page, now if someone wants to advertise on your fan page can just send you a message over facebook.
