Be very wary of the Google Web Accelerator/Interrogator. I installed it just to see how much improvement on my website surfing I would experience. Their OWN software showed I saved ZERO minutes in my web surfing experience. To save "ALL THIS TIME", look at all the RIGHTS you are GIVING UP from a screenshot of my install below!
1- Some web pages may embed personal information in these pages. Nice, now the GIANT has even more of your personal information at their fingertips.
2- Google receives and caches cookie data. Now they are telling you that they are saving your website cookies so they now where and when you surf.
3- Google may retrieve webpage content that you did not request. Great now I can go to prison because Google shows I surfed a website I didn't even SEE!
