>I agree with the issues, but it definitely doesn't suck if compared to every single other massive endeavor out there.

Compared to what? I dont really see much aggregation being done at all on Wikipedia's scale.

>What's the issue with that?

It's supposed to be impartial and objective and it sells itself as such but if you see how the sausage is made it is patently the exact opposite.

>I don't think there's a way to have an encyclopedic project without any cultural bias at all

I think it's perfectly possible to have an encyclopedia which is more liberal about allowing more sources to be used and which provides tools and metadata about those sources and gives tools to the user allowing them to filter accordingly.

Whereas "Blessing" one group of sources and condemning another will inevitably turn it into a propaganda outlet for whomever controls it. You might think that this is the only way but that represents more of a failure of imagination than a lack of options.
