There are various people who feel that Lesswrong degraded in the last year. In the same timeframe more and more discussions moved into the open thread model and open threads became weekly instead of monthly.
I suggest to counteract that trend by opening all discussions per default on Discussion instead of opening them in weekly open threads. Having the topics in discussion makes it easy to browse the list of topics and choose the headline that are of interest, even if the thread got opened two weeks ago.
Why do you think rationality quote threads have stopped? They're monthly, which means the next one should be up in a day or so.
The April one was posted in Main early in April, but I don't see a May one in Main and we're almost out of May.
