Currently, without adblock, i consider "The intranetz" to be utterly unusable.
So much spam of vile ads exists, i am literally forced into using adblock - because surfing the web for even 2 minutes without adblock is ABSOLUTE TORMENT.
Adblock for me is like a bulletproof vest for a soldier - i don't like having to use it, but without one i am just dead xD
I will continue using adblock for as long as it is needed, since without it the internet is just 99% garbage ads and 1% content you are after.
Addition:
Download something called Adblock Edge, it is a version of Adblock that does not allow any "white-listed" adds to appear.
