Have you noticed that Facebook is reposting Wikipedia pages? Apparently, they started doing this in April 2010.
Why are they doing this?
The announcements from the Wikimedia Foundation (via) and Facebook (via) seem hand-wavy at best to me. I'm more inclined to think Wikimedia took a "donation" from Facebook to play ball, and this is really all part of Facebook's never-ending effort to become the new AOL by trapping n00bz inside their walled garden, but maybe that's just me and my cynicism.
In any case, the main immediate criticism I'd make is this: the pages on Facebook don't seem to be kept up to date; i.e., they don't reflect the changes made to the corresponding Wikipedia articles. For example compare the page for Alfred P. Sloan, Jr.: Wikipedia | Facebook. Note also a compounding of the problem: Facebook also has a page for Alfred P. Sloan (the same guy -- Junior is the only famous one), which appears to be a fragment of the English version mixed up with an excerpt of the Indonesion(?) version.
Yes, each of these Facebook pages has a link to the corresponding Wikipedia page, but so what? If I have to go over to Wikipedia to get the latest version, let alone if I want to add something to it, why even bother reposting it in the first place?
Also, LOL: Time-traveler or zombie?
[Added] And in the department of Either That's A Mighty Weird Coincidence Or We're All Now Being Watched Always, I just got an email welcoming me to the Indonesian version of Wikipedia. Selamat datang!
