I keep stumbling across web sites that won't function if an ad blocker is installed. Any of the HGTV sites puke out when trying to enter their sweepstakes (the Boss' favorite past-time). I've now discovered that AOL's news marquee also will not work if an ad blocker is installed. I wonder when those blockers will figure a way to thwart the efforts of web sites to obstruct, break and otherwise render worthless their ad blockers.
