Plus there's the presence of the avatar block on the left at the top of each post, but point noted.
The sticky, closed, moderated, redirect, etc threads will get an icon at some point. Still trying to figure out what will work.
In terms of making sticky threads stand out, if you make them stand out too much, they actually get ignored; it's a common problem. We're trying to make them more subtle. The icon should make it easy to notice (rather than text).
The pages with the thread title are a work in progress. We understand using the last page as a "target", though it's nice to have a cleaner layout. We looked at demphasizing them until hover, but that has issues in IE (6 and 7 in particular)... which happens to be what you're using anyway.
