Facebook, IMO, is both good and evil and that's how we take it when dealing with it. It's a source of traffic and even "the Internet" for some, so we are now somewhat connected to it. On the other hand, it's a site that's robbing almost everyone of visitors now - online dating industry and most social networks are struggling. This can't be good - too much power in one pair of hands.
And as elcentcom said, we're not exacly supposed to buddy-up with FB all that much. Our own webhome.org see more is a movement aimed at takign down giant SNs as FB and bringing up niche communities, like those powered by Dolphin. On top of that we are, in way, behind a few hundreds of Facebook clones, so go figure.
Personally, I believe and hope that eventually online identities and social graphs will become independent and only content/niche communities will make sense. Facebook is just too generic to exist - their functionality should be a part of standard browsing experience, not a proprietary service. Our webhome.org and some other upcoming moves should contribute to making this happen.
