One of the reasons I prefer GMail for reading Mailing Lists is because
it groups threads and hides quoted text (but allows you to show them
if necessary). It's very clean. If you're using other clients for your
mail list subscriptions (such as this one), I'd recommend getting a
GMail account just for them, and setting up filters to label them and
archive them so they don't show up in the mail box (which is very easy
to do).

Heck, plus you don't have to worry about storage!
