So far, no "delete count". Though I can't say I won't implement something like that in the future. But if I did, it would be in conjuction with a "thumbs up/thumbs down" feature -- I want the Delete feature to be for purely housekeeping purposes, not a political "vote" of sorts.
It might be a really good feature -- say, more than 15 "thumbs down" sitewide and the post gets displayed with grey text instead of black.
You know, this isn't unprecedented. If you visit Youtube, you'll note the "comments" section does something similar. When a comment gets enough "thumbs down", they figure it's probably childish/rude/vulgar/etc. so they have a link that says "This message got a lot of down votes. Click here to read the comment". That way you don't have to skim through garbage.
I don't know if we'd need such a feature here -- maybe someday in the future.
