Get about 100k-120k/mon uniques with my tracking (http://pstam.com/i/ac2e01d23b0c4e03ba265bb271c03ab0.png), but its a far cry from when my blog was in its prime and would get 300-500k views/month. I've always wondering what I could make if I did that full-time...
as for "How do you monetise your blog? Just through ads? What kind of ads?"
I have a few streams, but I am far from whoring my blog out with ads so my $'s are conservative. Mainly I have an SEM firm that sells ad space on my site, affiliate stuff for my usenet host and affiliate stuff for the theme my blog is based on. Everything is relevant and tech related.. no random adsense.
Pretty well known and according to Compete.com seeing about 55k uniques/month, thats quite a bit.
