I used some to test adwords, and also to have access to how much is each word ;-) I like adwords , I got some traffic and get new people to my forums, so it was worth the price I suppose I do not use right now, but in future I am sure I will. I also bought a pair of domains.
First check ??? Pay my hp and internet bills.. gotten my 2nd check today.. gonna pay my credit card bills...haha.. the devil card
My first Adsense check was only about $200. I think I just put it in the bank. Not very interesting, I know.
Too small to spend the money on something that I had dreamnt of (It's a 350 D canon DSLR). So I spent it on food with friends and families. @angellica gave it to mom? it's very nice
