I've already given a few thoughts on Wikipedia (here and here) but Martha Nichols at Athena's Head, has few worthwhile words on the topic as well. It's worth the read.
The piece begins, "Much as I appreciate Wikipedia’s Book of the World and its many temptations, I’ve come to see it as a geek Satan." [...]
Yes, you know me, too. I hate looking clueless, especially in front of my eight-year-old son. But what I hate more is losing the foundation for all truth in a constantly fracturing informationscape. And now I find that one of Wikipedia’s founders, Larry Sanger, would like to disown his creation.
*However, here’s Problem Number One: Wikipedia entries employ the “objective,” third-person voice of the expert, yet Wikipedians are “largely anonymous” according to the site.
