EDITED: Seems like the EA Forum is becoming the place where wiki-style information on EA is being curated, so I'm phasing out the EA Wiki in favour of the EA Forum Wiki.
Isolation got you stuck at home? Help out with the new EA Wiki!
This is a new project. I copied some of the content from the old EA Wiki and pruned a lot of it (as much of it was out of date). The Forum is great for getting the latest updates but not so good for finding out the consensus on a particular subject; wikis are better for driving this.
I'd love for the EA Wiki to become the go-to source for EA knowledge. Sign up now!
I've not attempted to consolidate other wikis - I think the LessWrong and Cause Prioritisation wikis are best kept separate. Concepts also hasn't been touched in a long time as far as I can see. My hope is that simply by not going offline or being unavailable this wiki will be the default Schelling point!
I also think the fact that this is run on MediaWiki (the same platform as Wikipedia) makes it more familiar/easier to get started, but I could be wrong.
Your point about reputation is very right - need to think more about ways I can surface people's contributions.
