Okay guys, this is something that really bugs me. Regardless of whether you know of this or not, Ad Block is a browser plugin that lets people block all kinds of advertisements from being shown INCLUDING Google Ads, full page ads, flash ads, affiliate ads, slide in ads, pop ups/pop unders, and yes including contextual ads.
It really p:sses me off that such an application exists because such ads allows websites to be up! Owning and maintaining a website and/or eBusiness is NOT free, and isn't easy either. I just really wanted to hear other peoples' opinions regarding the subject, because when I see my forum users discuss it, I instantly warn them that if they use it to browse my site that I will ban them. I do offer premium memberships that don't see ads for very cheap.
