I've never been to wikinews before, but it looks like exactly what I was talking about. They have a prioritized list of articles that need to be reviewed for bias and accuracy, so that's really good.

My impression of the economist is that they are unashamed and forward with their perspective. You read it and you get "this is a neoliberal perspective and these are the arguments of of neoliberales." So yes, they write from a very clear perspective, but it doesn't feel like bias creeping in. Instead it feels like "this is what this situation looks like from this perspective." Bias is trickiest when it's hard to tell where someone is coming from, and with them I never have a problem.
