Like an email chain that keeps adding Re in the subject line

Ok, so that's why people want threaded view? I've always thought that was puzzling, as I don't use it myself (neither threads nor Google).
Gmail might have gotten the inspiration after they purchased DejaNews and made the Usenet archive into Google Groups. Just a guess.
Usenet was always threaded in the clients I used back then. But for somme reason threaded email does not work for me, personally.
Gmail has a thing I don't know who else has. The emails are categorized in General, Social Networks, Ads and Informative Updates.
