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.
LW exist for allowing discourse to refine the art of rationality. It's purpose is not that everybody can share whatever is on his mind.
Editorial and moderation choices are going to be directed by that goal. It's different than a medium like facebook that exist for everybody to share anything.
I doubt that's technically true. The Iranian government is going to punish speech by it's citizens that it doesn't like regardles whether that speech happens in Iran or whether it happens in another country.
