Anyone know exactly how long it's been?
Its been more than 2 years (iirc June/July 2021) since the last merit source readjustment.
Theymos seems to be so tight-lipped about anything to do with the merit system that I don't even have a sense of whether it's doing just fine or if it's at risk of falling apart (though I don't think it's anywhere close to the latter).
Before he introduced new merit sources and increased monthly allocation to already existing ones, number of merit shared per month dropped significantly (prior to june 2021 it was half of the current amount) and since merit numbers are pretty much stable since then and there was no significant decrease (add on that the fact that at the same time number of posts dropped down) I don't think that we gonna get new merit sources anytime soon.
Another problem is that themos usually doesn't approve merit applications individualy, but he tends to do in bulk when he does merit readjusting which makes it even a longer wait.
