google adsense?
 

how are some of you guys doing with it? does it make money?

Yup.. I make money advertising google ads on my mainstream sites and I also make some money (not a lot.. ) buying keywords for weird little niches and sending them to some awesome little sites.

I use it for a few sites, works well.

I wish there was an adult adsense..

googlw allows you to do adsense for adult stuff! I think.
