Fediverse

Wikipedia doesn't replace books. In my comment at least that's why I was specific about "general information". I think everyone must be aware that when it comes to Wikipedia on history or current events, it will largely be from a liberal and pro-west perspective. Not all the time, and usually the references and further reading sections point in more interesting directions. But this is far more valuable than the most boring so-called Marxist wikis. If you want critical history, go read historians like Gerald Horne, read first-hand accounts from journalists like Edgar Snow and so on.

Besides the purely political, wikipedia is also good for overviews on technical and scientific interests. Even with the negatives of wikipedia, I'd take it any day over some decentralized spam fest where its a gamble if you found the best version of some article. Not to mention core issues of the fediverse, such as whether the hypothetical wiki instance you found yourself on will sustain itself long-term.

Some days I wonder if the core Lemmy developers have drifted further towards anarchist politics and philosophy..

No, for the same reason forums can't replace reddit. Self hosted wikis have been around before and after fandom. The reason it became popular was giving you all the fandom wikis together, one account, discoverable, user friendly so regulars can contribute. If I have to sign up to every fandom wiki I can contribute to, learn a new interface (likely something old and not mobile friendly) and rebuilt up any reputation to gain extra editing rights... I just won't.

Ibis then in theory allows you to use one account, federate your reputation, use one interface, with lots of third party options if you don't like the official one (if lemmy is any indication) and have discoverability of new wikis.
