>It'd be very useful to selectively exclude posting from specific users (I'm sure there are plenty of people who like to ignore me! < g >) I understand that adding this level of filtration would be expensive - in essence, you'd need to construct a "block list" for each UT user - but it might go a long way towards providing a useful improvement of the S/N ratio from each user's perspective.

An extreme, but interesting, idea.

I think I would prefer the option to somehow mark a thread so it doesn't clutter up the top right pane. However, even more expensive than your idea (unless it could be leveraged off the existing mark thread capability).
