Normally, about 100-150GB a month, but that was on my old 1.1mbit connection, and was mainly BT. Now I'm on a ~15mbit connection (ADSL2+), and hae re-discovered usenet, and am in the process of working out which provider I want to go with. At a guess, I'm going to say I'll be leeching about 300Gb a month to begin with, then probably drop back down to 150GB again - I get bored of downloading!
