I can talk a lot but let me just let the images do the talking.
Check out these two images to know how awesome Adblock is:
[ Chrome with Adblock ]
[ Safari without Adblock ]
Why would these websites make me go through option #2?
Some news websites )now do not show me the page till I unblock Adblock. Given the quality of the experience, why would I bother? I can access the same content through other sources - simply google the same headline and you will get other options. So it is really their loss if they put these hurdles between me and what I want!
