Now, I've never seen Times Square immediately after a snowfall, but I have to say that experiencing the web without ads - or at least with a whole lot fewer ads - is awfully pleasant. Imagine that somebody has been yelling into your ear for so long that it's come to seem normal. Now imagine that the person suddenly shuts up. That's the effect of ad-blocking. It's like going back to the feel of the web in the early 90s, before it was strip-malled.
Webmarketers may feel a sting of guilt, however. After all, if everybody did this, many services, such as search engines, would cease to be.

I have use that before and I see that's all adsense contents I saw in many sites are gone.. I thought Google is updating their adsense.. Adblock is the reason why they have disappeared... I just remove my adblock add-ons...

Now I see adsense...Thanks for the info...

Mixed bag, unfortunately I've found a few good services due to ads, so I'll never block them out. There are a few advertising methods that I would like to see banished, but overrall...it makes the world turn.

Lastly, only a small percentage of people will ever actually learn to 'block' ads, since the majority of internet users are unaware of such things anyway. Depending on your target audience, it may have no impact.
