Organized Learning

[Artist]

I recently came upon a website called Stumbleupon.com where there is a
small toolbar to download and you get different website each time you
click the stumble icon matching to your interest and then you rate the
website etc..
full detail at www.stumbleupon.com

Question: How we can converge the theme of the application with emacs
to learn new emacs things or even the emacs newsgroups or posting of
featurs.

Thanks,
artist.
