You're not looking hard enough, you'll find & wherever it is used in my
websites, and anyone else that writes valid HTML. You can find pleny of such
websites after browsing the W3 HTML validator mailing list archives =)
btw. it is more than a recommendation, an unescaped "&" renders your html
invalid.
Finding invalid HTML on the web, however, is all too easy try :

http://www.bell-labs.com/ - which even has invalid utf8 !
