Facebook will be making your fan pages public

I recently saw a notice in Facebook warning me that sometime soon the companies, products and people I'm a "fan" of in Facebook will be made public in search results. I'm not sure that I see the user benefit here, but the obvious marketing benefit is to raise awareness of fan pages and get more people to become fans of more things.

You can opt-out of this by unchecking the box in your privacy settings. But it looks like it will be turned on for everyone by default (and retroactively for existing users).
