@Gunner: It's ad blocking software (it hides all ads in a page).

Benefits include:
 * faster page loading (because loading large flash-like ads no longer happens
 * less distraction

Downsides:
 * sometimes more memory consumption (I'm at +20mb with 6 tabs open). this generally isn't a problem, but with large pages and multiple (20+) tabs open it can start to be a drag

Ran some metrics with the CAW Main Page

Without adblock:
 * completely done loading page in 20.95 seconds
 * onload fired after 6.61
 * DCL at 3.69s
 * Max RAM for Rendering (CSS) usage @ 68.62 MB
 * Sustained RAM @ 141mb see here
 * page snapshot

With adblock:
 * completely done loading page in 8.4 seconds
 * onload fired after 6.12s
 * DCL at 4.26
 * Max RAM for Rendering (CSS) usage @ 23.6 MB
 * Sustained RAM @ 87mb see here
 * page snapshot

If you're using chrome, you can get it here.
