Adlesse for Chrome
More About Adlesse
Adlesse substitutes the annoying banners for useful widgets of the same size.
Currently, you can substitute ads for several types of info-boxes: local weather conditions and forecast, news headlines, interesting facts, famous quotes, your Twitter and Facebook feeds and interesting links shared by your friends.
Also it fills ad space with your friends' latest tweets when you're logged in on Facebook and search results from Bing, Wiki and Twitter on the Google search page.
Unlike other ad filters (such as Adblock) Adlesse doesn't prevent the ads from being loaded, but hides them. With only one click you can see the ad hidden under any particular widget. It prevents you from losing access to the important parts of the page (such as flash games) by mistake. Also unlike AdBlock Adlesse doesn't block non-intrusive text ads (such as AdChoices by Google) that most people find helpful.
