Aye, seems like a little nasty propaganda.
I'd expect that since most reputable internet mail sites use HTTPS and therefore your browser & the originating site must handshake with a particular private key first, it's crap.
On the other hand, it gives them a very easy tool to profile peoples surfing habits & hence the best abilty to sell ad's as required
I don't quite understand how the caching works If an internet connection is slow, it's slow Unless google mirrors the entire "Popular" web on each local server, or has it's own private cables & hence privatised bandwidth between nations, then it's not likely to be significantly faster
As I'm neither a mod or admin, I cannot comment on whether CDfreaks uses HTTPS or some other form of security against caching
But at any rate ..
Google is BIG BROTHER
