By using tools like MSN, hotmail, Yahoo mail and IM (and yes, also google’s suite of tools), you are constantly leaking identity data to these companies: chat doesn’t go from you to your talking partner. It is send through the servers of those companies, just like mail, and nobody knows where all of that ends up.
With Microsoft now stepping up to get it’s teeth into Yahoo, it’s time to let go. I am ditching my yahoo account and affiliates
Yahoo! Mail , Yahoo! Address Book, Flickr, Yahoo! HotJobs, GeoCities, Yahoo! Briefcase, My Yahoo!, Yahoo! Groups, Finance Portfolio, Any other area of Yahoo! that can only be accessed with your Yahoo! ID and password.
Here’s the link, I had some trouble finding it.
Note: for secure end to end encrypted voice and IM, I am using Skype.
