Lefty wikipedia: leftipedia.org
The site conservapedia.com, which is written from a Christian and American conservative viewpoint:
has received negative reactions from the mainstream media, as well as from notable political figures, including commentators and journalists, and has been criticized for bias and inaccuracies. (source: http://en.wikipedia.org/wiki/Conservapedia)
http://www.dkosopedia.com seems like it’s not getting much care; I was unable to create an account or login with my daily kos credentials. Its name isn’t descriptive; rather, it’s cryptic and insular. I didn’t comprehend the connection to daily kos when I first saw it. It has over 14,000 articles.
http://left.wikia.com doesn’t have a nice name either, in my opinion; it’s hosted on a wikia.com, which has ads, and it seems derivative and vanilla. It has less than 4000 articles.
The name leftipedia.org is superior, I think.
Perhaps the contents and contributors of these sites can be combined. Writing quality content is a lot of work, and managing, moderating, and paying for the site is a lot of work too. But better for it to be crowd-sourced than for it to be controlled by a few.
