The NYTimes blog The Lede has an interesting post about Wikipedia's reaction to Representative Joe Wilson's yelling 'You Lie' at President Obama last night. I can't put it better than they can, so I suggest you give it a read.

From my POV, there are two interesting dynamics going on here. First is the question of whether Wikipedia should be a news source. Unequivocally, it is a news source. But I think many in Wikipedia's heavy editor community act on an ideology that classifies Wikipedia as an encyclopedia, not a news source. This is myopic at best, delusional at worst. It also provides a nice illustration of why ascribing attitudes to the "Wikipedia community" as a whole is misleading. The most vocal Wikipedians, the heavy editors, often hold tight to dogmas that aren't representative of others' attitudes.

The second, related issue is what Wikipedian's call 'Recentism'. If you go to Joe Wilson's page right now, you'll see a funny little notice at the top that says "This article or section may be slanted towards recent events. Please try to keep recent events in historical perspective." Here's the thing: I think this a sound sentiment, and good advice. But again it reflects that clear dogma about what Wikipedia is and what it should be. How can Wikipedia really be "neutral" when it has deep-seated dogmas and policies that restrict and direct not only its content, but how people should use it?
