Has been a lot of open threads in the past, but not recently. It is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets good enough, open a new top-level post. Besides, I have an issue to discuss it here. Enjoy!
This got even weirder than I thought. When I came to log in, I made an account and typed my first post as OtherDavid, and just before hitting send noticed that one of the most recent comments in the sidebar was from TheOtherDave.
My new username is an attempt to be slightly more distinctive within the Dave subset 'people referencing they are called Dave'.
It's not LW's fault, mind. I recently started a new job and was the third David there, in a team of under 20. I didn't want to be 'Dave' or known by my surname, so ended up calling myself D3.
