Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
It seems to me, despite talk of change, LW is staying essentially the same... and thereby struggling at an accelerating rate to be a place for useful content.
My current modus operandi for LW is to use the LW favorite I have in place to (1) Check SSC and the other "Rationality Blogs" on the side bar, and then (2) peruse discussion (and sometimes comment) if there isn't a new post at SSC, et al that commands my attention. I wonder if other LWers do the same? I wonder what percentage of LW traffic is "secondary" in a way similar to what I've described?
I like your suggestion because it is a radical change that might work. And it's bad to do nothing if what you are doing seems to be on a trajectory of death.
At some point, during a "how can we make LW better" post on here, I mentioned making LW a de facto "hub" for the rationality blogosphere since it's increasingly not anything else. I'm now re-saying that and seconding your idea. There could still be original content... but there is nowhere close to enough original content coming in right now to justify LW as a standalone site.
As a a data point, this is exactly how I've been using LessWrong for at least the last year. One of the reasons I more frequently comment in open threads is because we can have less idle conversations like this one as well :P
