OK, that's not a linked story. But I thought it's really worth sharing. I was looking for some specific proof about locally compact spaces. And to my very surprise I found Pr∞fwiki
[proofwiki.org]. It's a site full of wonderful mathematical proofs. It's crystal clear, or at least aims to be so. Much clearer to read than wikipedia, which in my opinion tends to be full of various things except ones that can be directly verified, just by reading it and checking the proof. By looking at history I see that it's operating since roughly 2009. And it needs our help, of course. When I will find some proof I will definitely add it there! Will you?
