Quite a number of people
As a college student I download anime from other people through DC++. I get 700kbs typically.
You can also download at 300kbs from IRC.
Currently I'm at home from spring break and torrenting some of the stuff I couldn't find on DC++ or IRC (KAA's rip of Black Lagoon specifically).
There's also direct download from sites like baka-wolf.com
I've gotten 400kbs from that site before, but it can be slow sometimes (and only offers limited selection).
Megaupload is another option. anime-sensei.net
is an example of a site that collects anime megaupload links. Megaupload has a set of problems as well as limited choice, but it does the job eventually.
Of course you could always buy/rent the DVDs as well if there's some old licensed shit you want to watch ^^
