 Horribly OT, but I keep wondering about the overhead of that. There
 must be some grunt-work involved just to see if a URL matches
 something in its block list, however minor. With the enormous list of
 sites / domains that it must have to filter these days, that overhead
 *might* be noticeable to a user (vs. what it would be like if there
 weren't the offending items in the source markup in the first place). 
 What's more noticeable?  Waiting for 3-4 large bandwidth consuming ads
 to load from various places while 1x1 pixel flash and images load from
 3-4 other places and various tracking cookies to be set and fetched so
 that animated targeted ads can bounce up and down, or processing every
 HREF through a filter in memory at CPU speed? 
 If anything I'd bet that the CPU power wasted on displaying animated ads
 is far higher than that "wasted" on a bunch regexps preventing that crap
 from loading in the first place.
