This Greasemonkey script makes comment threads a bit more pleasant. The idea here is to make some comments less important than others in terms of screen real estate. Comments you have seen already or comments from guests can be minimized so that you scan right over them.
If you track LWN threads often and you want to see only the new stuff, then this is the script for you. Personally, I rather like the simplicity of LWN, but it can get a bit hard to follow the busy threads.
