Adverts

Do you find yourself annoyed by them? Do you enjoy some of them? Do you ever click on web adverts? Or do you have some strategy for avoiding them?
Adverts can often provide some much needed income to keep a website going (this isn't just a shameless ask - but if you see an advert that interests you and you click it I do get a (very very) small reward). Do you use tools like Adblock.
Just trying to gauge opinion on whether it is of any use keeping the adds on my site.
