Indeed, referers are useful information in some cases. For bookmarking apps like http://noteplz.com http://noteplz.com one useful thing is that along with the bookmark, they also store the referer, so you can later go back to the google search result where you found that bookmark. On the other hand, with https and url shorteners,referers are a dying breed. The situation with URL shorteners is absurdly funny now, because twitter double-shortens the shortened urls, since most popular sites have their own shortener.
