So far this month I've used 700mgs for my website. That is with posting some offsite images (takes up more bandwidth) plus whatevr myhostees are doing. 2 gigs isn't bad, especially for a blog thingie.

(I could give you a free space though if you ever want one)

Anyway, it's usually when you get into offsite linking (like if I posted images from my site on this site) that usually gets the bandwidth down, but even then 2 gigs is pretty good.
