It's a different web without adblock, and it's not pretty one. It does more than just hide advertisements, it also reduces bandwidth usage considerably. I've been using adblock since I was stuck on dialup. It was critical to me back then to make pages load faster. Then I was on satellite and adblock helped keep me under my data allotment. On the rare occasion that I have to use a computer without it, I'm always taken back by how bad the web is with all the ads. According to some estimates, we're exposed to over 3000 marketing messages every day, on average. I'm all for anything that reduces that number, whatever it actually is. Every person that I show Adblock to, has been very, very happy with the results.
