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.
Interesting opinion. I rarely browse open threads, mainly because I find them a mess, and it takes a longer time to find if there's anything which would interest me in there. Discussion posts have their own page with neatly ordered titles, you get an idea at a glance, and can on a first filter sort through around 20 topics in around 2 seconds.
