Google adSENSE???

Does it make sense to have google adsense or infact any other online advertisement thing on ur blog/site like ADbrite if ur basically gonna have very few visitors ??? I'll try giving u an answer through this pots..
hmmm i just started blogging and for the heck of it i put advertisements on it very well knowin that i wont make more than a dollar a year..present earnings $0.08 :p..so the question y did i put it?? initially when u start off u have the feelin that i can make some money here but then u soon realise that u earn $0.04 per click on the ad and on top of that very few people visit ur site/blog and another constraint if ur a person like me ull never ever click on any advertisement..The goin is tough especially when ur site/blog is very average.At the best ull end up making a few dollars a year..do i need those few dollars?? i dont but then y am i putting these ads...the day i have an answer il let u know..till then il keep hopin to become rich and hummin the song "sabse bada rupaiya"...

PS:-Anyone who wants to put up the Adbrite ads..there will be a tab on the right handside saying "adbrite monetize ur site"..do click on it ill make some money :p
