Adblockers are borne of intrusive ads. If they were sidebar things like they used to be I'd be much less inclined to use one and just let them collect their ad revenue. Nowadays though there's gotta be a video, a video embedded at the top, a pop-up ad, a break in an article every 10 lines of text for an ad, and then a delayed popup for when you get halfway down the page, PLUS the sidebar and banner ads.
Exactly, sidebar and banner are fine. If that's all I see I'll let it slide. The ones that make you stop reading to chase down the little black "x" on a pop up or separate the text with a wall of ad, fuck that shit.
