I thought everything Zuckerberg ever built was based on scraping other peoples' data. Even now, didn't they pull info from Wikipedia for their pages about your interests?
Ok, I've never read their terms of service, until now. I'm guessing they have provided credit to the actual authors with a link to the original article and included a licensing notice? (not on Facebook)
Wikipedia's Terms of Use basically just guide you to act in a manner compatible with the Creative Commons Attribution / Share-Alike license, as well as the earlier GFDL license. (I am not a lawyer, probably there are significant additions, that's just my take on it).
Facebook could have scraped Wikipedia without asking, but as it happens, there is an agreement in place. I happen to work at the WMF, but don't ask me for more details, I'm not that privy to them.
Interesting. The thread certainly makes it seem like it will be mutually beneficial. Maybe Facebook is a little less evil than I think, considering they gave a heads up.
