HD Webdev's Journal: Google Web Accelerator

Don't use the Google Web Accelerator if you block advertisements with software and/or a hosts file.

Their accelerator will bypass software advertisement blocking programs and hosts files set up to block advertising. Google should have mentioned this on the Accelerator Help/Support page.

They did not do so and couldn't have missed this side effect of their accelerator.

I'm very disappointed in Google for doing this sort of thing.
