If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
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.
Thank you! However, this appears to miss anything that is "Promoted". The only recent example is Free CFAR summer programs, and before that the LW survey. If other posts get promoted they may also get overlooked by browing from Discussion.
Main is still a separate section, even there isn't much happening there.
You can get new posts in Main from http://lesswrong.com/new/
There may not be a convenient way of tracking new comments on non-promoted posts in Main.
