Thanks to Russell Brown's Hard News, I've recently discovered two Christian web resources, GodTube.com and Conservapedia.
Conservapedia claims Wikipedia is biased, anti-American and anti-Christian; that's why they need to reinvent the wheel (while copying the design verbatim from Wikipedia).
While the site looks lame, I can understand the perceived need to set up your own game if - and that's a big if - the claims of bias are true, and if you have enough volunteer power to create something as extraordinary as wikipedia. Otherwise, just do an ordinary website, don't call it a wiki.
But GodTube - why?? As far as I know there's no rules against posting explicitly Christian material on YouTube. It's a very nice, slickly presented site, but it makes me think of what a mistake Christians make when they lose track of the mission - to love God and love your neighbour - and instead set about building a deeply irrelevant subculture.
I heard a brilliant sermon recently on the Emergent Podcast about "finding our God in the other". It asks, why are Christians uncomfortable participating in conversations we cannot control? It's an honestly asked question, partially answered in a respectful, challenging and thought provoking way.
