:-D Let's try it
I don't think they could enforce their trademark if there was a Hackerbook. Throwing tons of money and lawyers at it can make somebody back out, but they shouldn't be able to have exclusivity on [anything]book even in the context of social networks.
Maybe we should :) Although I think hackerbook.com would be a better name for some sort of collaborative book project.
I get what you're saying, but if you look at it from Facebook's point of view if they don't defend their trademark they'll lose it. If there are looks of [something]book.com social networks then [something]book.com just becomes a generic term for a social network. Facebook then loses the right to claim any sort of exclusivity at all on their trademark (I think that's how it works anyway, IANAL obviously)
They wouldn't loose the right to facebook, only to book.
So somebody could make sexbook (properly already could if it was not a social network, but, say, a book about about porn) but they couldn't make facebookofsex.com
