I like ads because they are a great way to monetize things that you otherwise couldn't. I prefer to donate to sites I like to use, but not everyone will do that, and if a site gets a lot of traffic, ads can bring in a lot of extra revenue. Reddit has Reddit Gold, for example, but still has ads as a way to monetize lurkers and very occasional users. I would probably not block ads on Snapzu unless they were flashy, obtrusive, noisy, or pop-ups. Pop-ups are an instant block from me - sound too - but in general, I like to let a site passively make money off of my traffic.
