Larry Sanger apparently co-founded Wikipedia but I've somehow never heard of him before. Not sure how that escaped me.
He's apparently famously critical of Wikipedia. The majority of this article seems to complain about giving facts undue prominence over a "balance" of viewpoints.
What's the opposing viewpoint to the truth? Lies?
(And his political bias really shows. The Obama article is too positive. The Trump article is too negative. The article about abortion doesn't say how evil it is. And the global warming and vaccine pages don't report enough on "minority viewpoints". It's amazing how consistent the beliefs of the far-right are.)
From my non-expert perspective, Wikipedia is doing a surprisingly good job. Even this article actually gives me confidence.
