Go to any page on stackoverflow.com, open firebug (or use some other html searching feature), and put in "everyonelovesstackoverflow" into the search bar. There's one div in the html with that class (second child of the sidebar), its contents are thus:
<script> tag (in little pieces?) into a document. When I put in ads.stackoverflow.com, it takes me to a login for a stackoverflow advertising page, so I'm guessing they're references to a script that shows an ad on the page.
But perhaps foremost I'm asking if this is a bug. Its an odd name for a div on this well designed site, and the div never seems to have any content. ever. The only other reference I've found to this div is this question, in a greasemonkey script that reverses the reduced advertising when you hit 200 rep, so I thought it was an add. I've disabled ad-block plus and greasemonkey, logged out, and visited the site, and the div still has the same source-code, but nothing ever appears in it. Can anyone else see an ad in that div? (as my cookies or other factors could be interfering with what I see). This just smells weird, can anybody give an explanation?
EDIT: OK, now I see the ad. Maybe I'm just being an idiot,
