Yes, I know we had a talk about this not too long ago.
To be honest, though, the reason I have the ad blocker was because I was so sick of seeing all those Evony ads everywhere. That advertiser seriously needs to stop it, for their ads were just horrible. Completely distasteful, and they had absolutely nothing to do with their game at all. But because of that, and a few sets of annoying ads, I just installed the ad blocker and thought nothing else of it.
I don't think people realize this can hurt the sites they visit, though, so talking about it as you are may help. In my case, I visit Techgage all the time, but forgot my ad blocker was even on- that's how well it works. And as I mentioned to you, I saw no ads on the site, which does make it look a bit barren. At first I wondered why, then realized oh, duh, ad blocker. I did turn them back on, because I do wish to support Techgage. I'd like like to support the many websites I visit, just because I know how hard it is to run and manage things. It all costs money and time, so having ads is completely understandable.
However, I also believe that the user shouldn't have to put up with those annoying ads either. I know you said you'd never use such ads, but other sites change them often, many getting to the point of being inappropriate or intrusive.
So I can honestly say I see both sides of the issue.
