As long as you remember that it is an encyclopedia then I think it's actually pretty good. Yes, lots of the pages about contemporary political issues are full of CIA-posting, but you really shouldn't be trying to get your political news (or understanding of theory) from an encyclopedia in the first place. That's not what they're for. Similarly, I think it's fine that most of the articles aren't written at much more than an undergraduate textbook level of sophistication. Again, if you want expert-level specialized knowledge about a complex topic, an encyclopedia shouldn't be your go-to in the first place.

I think Wikipedia is fine, and I agree that it's one of the few good things that remains on the internet: it is advertiser free, not paywalled, not run for profit, and freely accessible. It certainly has a strong bias, and the fact that people on will take it as the gospel truth about literally everything is incredibly stupid, but if you treat it as the very general tertiary source that encyclopedias are intended to be, it's fine. This is one of my views that's out of step with what seems to be the Hexbear consensus.
