Just be careful with Adsense. You don't want to get too many views or clicks within a small period of time. Also, watch out for your refs, you don't want Traffic Exchange sites there since they're against their ToS.
I have over $100 in my Adsense account but I cba to link bank and do tax information crap. I pretty much started just before the whole blogger craze on 4chan, then when it came, I used blogger threads on 4chan to boost me. I still see some threads every now and then but it isn't like it use to be where every page had atleast one thread.
