Something about this bothers me too. I am trying to formulate a way to look at this that gives Facebook the benefit of the doubt, like "anyone you can help is good, even if you can't help them all"... but there's a pessimism in me that says Facebook is being opportunist.
For a site this ubiquitous, they don't need to scrape the bottom of the barrel to get a few more page views -- I think this is earnestly meant as a service to others.
I don't have a Facebook account, so I can't verify, but at least on that landing page, they're not serving up advertisements.
