As time goes on, I trust it less and less on many subjects. I guess it’s still ok for ‘settled’ science (if such actually exists) and for a lot of history; but it’s useless for anything the least controversial, including politics and very recent history.
I’m especially interested in some things that might be considered ‘fringe’ science but which I believe have value regardless; and the ‘guerillas’ have completely destroyed Wiki for most of that. They are hell-bent on shutting down any speculative thought in those areas. (Rupert Sheldrake and bernard Haisch are cases in point.)

Good examples—and there are many many more.
Modern physics—including quantum physics, quantum mechanics and astrophysics are in turmoil these days—Kurt Jaimungel has some great discussions with many physics and math experts in his “theory of everything” podcasts/videos.
Wikipedia is deep in denial on all this stuff. They accept only the “official” version—no matter how outdated and debunked it may be.
