Since these are not true, and they keep getting repeated, I will relay the real state of the unofficial wiki: It is being maintained by @fadenb who has replied my emails in the recent past. It has a non-empty admin team of undisclosed participants, and it has editors (I contribute to both wikis). But the unofficial wiki does not have a wiki team, like the official wiki has, and it sees about 20-30% the edits of the official wiki last time I checked the stats. Most of the articles are exactly the same from when the official wiki copied them ~14 months ago.
So… relying on wiki content: That’s highly dubious either way; there’s a slightly higher chance the unofficial wiki’s content is a bit more outdated, but also a higher chance it wasn’t link-jacked because it has rather good anti-spam protection, since it was defaced by the official wiki’s founders early last year.
We can certainly discuss if the state of the two wikis turned out ideal, and if it could have been handled better. But we cannot deny the fact that there are two actively maintained wikis run by two teams with competing pagerank, and the only people who suffer are newcomers. Let’s not increase the misinformation to “help” people.
