Oh gods, this is another Vox Day's ego project?
Vox Day doing anything without bias is like building an ocean without water. I'm not saying he's always wrong, but I will say he is probably one of the most biased individuals on the planet.
That said, wikipedia is a great resource if you stay away from current events. Hard science stuff tends to be pretty decent. History is usually decent, if taken with a taste of salt. Current events or persons? Any change to any current person or event should require a three person of opposite ideologies signing off said update before it goes live.
It'd be nice to have a higher quality alternative, but many have tried and all have failed for various definitions of failure.
