It is really frustrating that there are dozens of complaints about inaccuracies and awfulness of articles in wikipedia with none of the complainers able to provide a single example, there are 100s of comments with zero example articles at all.
I work in ML and have found wikipedia to be a very important reference when I do any research. Which is what an encyclopedia is supposed to be.
On Wikipedia's entry for Facebook, there's no discussion in the 2006-12 section about Facebook's steps to monetize the site around targeted ads. That has had gigantic global impact and was the impetus for Meta/Facebook's emergence as one of the world's most profitable companies. But Facebook never "announced" that it was doing this. So the entry is clogged with a string of quite minor "announcements" that it did make -- touching on short-lived headquarters moves, feature tweaks, obscure awards, etc. instead.
Wikipedia's entry on Maine Republican Senator Susan Collins is an achingly long list of votes she's taken over the years, or one-line quotes about her positions at various moments in time, without any effort to write coherently about what's been consistent or evolving in her political views. Also absent is any nuanced sense of how Collins's journey interacted with changing political tides. We end up with a 20,000-word string of factoids that goes on forever, with scant insight about her enduring impact, core principles, etc.
There is a whole section and separate article on her political positions.
As an encyclopedic reference it looks like a pretty good reference. Obviously a strong narrative like a new Yorker profile can't be expected of an encyclopedia.
Actually, back in the day, that's exactly what the top encyclopedias aspired to do. It's worth looking up who wrote the main entries in the 1911 Encyclopedia Britannica. Future Nobel laureate Ernest Rutherford did the entry on radioactivity. British medical researcher Joseph Lister (the inspiration for Listerine), wrote the entry on slime molds. Environmentalist John Muir weighed in.
And, in my absolute favorite, Russian anarchist Peter Kropotkin wrote the article about anarchy.
