Presumably folks at SI are discussing these issues independently of the discussion on Less Wrong; they don't seem to be posting here much.

I've been complaining about this too. But it does seem that SI is more open than before (e.g., lukeprog's recent series of posts on future SI plans), which we ought to give them credit for.

It seems to me that posting your arguments on Internet is a good way to get falsifying evidence for them. If the box does not contain a diamond, I wish to believe the box does not contain a diamond and whatnot.

Strongly agreed.
