OK.  Some more data:

cnn.com: ~3e3 elements.
gmail.com: Might depends on the size of your inbox, but for me
            right now 2.7e3 elements.
CSS Selectors level 3 REC: 2e3 elements.
Empty Google Docs spreadsheet: 3e3 elements.
jquery.com: 3e2 elements
41e3 elements.
39e3 elements
github.com: 1e3 elements
https://github.com/jquery/jquery/blob/master/src/core.js: 3e3 elements
https://github.com/jquery/jquery/blame/master/src/core.js: 5e3 elements

For what it's worth, slow-selector issues have come up before on github 
pages; see https://bugzilla.mozilla.org/show_bug.cgi?id=732667 for an 
example.  That link is now 404, but based on comparing to the jQuery 
pages I doubt it was more than 10e3 elements.
