Google Web Accelerator claims to speed up downloads (with only minor invasions of your privacy). NewMexiKen is giving it a try and so far it claims to have saved me 39.6 seconds. Of course, that’s in one and two second bites, so it’s difficult to assess.
Besides don’t most people browse at work to kill time?
Update after six hours: It’s probably just me, but I sensed that this thing was slowing things down. I removed it already. We’ll wait and see.
