I was half thinking of reviving that thread just to get LH back for all the silly Shatner ones. I was afraid of all the potential curses.

Back to the original question. I've been hanging around here for a year now & there's always been a fair amount of thread reviving. I haven't noticed more lately than usual. Have you noticed that they are of a particular nature?

Not long ago there was a thread called "Origins of: Found on Mudcat" with links to past interesting discussions. People following those might be refreshing those they find most interesting.
