I disagree. Reading the messages in chronological order is natural and
if people quote their parent posts properly, which they nearly always
do, there's no need to consult the parent message again (and you'll
have already read it by that point in the conversation anyway and
recognize it). Why would you "grab random posts" anyway? It makes much
more sense to just read the stream until you reach an interesting post
(thus gaining the context of the _entire_ discussion) or just read the
post in isolation along with its quoting of its parents.
Additionally, for most normal people who've never heard of
mailinglists, email conversations are typically simple back-and-forth
exchanges displayed excellently by Gmail's conversation view; these
same people would probably find threading complex and confusing.

Yes, apparently circa Netscape 3.0 they used an ingenious message
threading algorithm (described on
http://www.jwz.org/doc/threading.html) but the Netscape 4 devs
foolishly threw out the code and wrote the broken algorithm used
today. Quite a shame.
