The Riffs social commentary site. Kind of a cross between Digg and Epinions. Log in and rant or rave about anything you like. Your commentary in turn will be voted on, and so it goes. You know what…I like it. I’m not sure that it adds a *huge* amount of value to my life, but maybe it could develop into a cool kind of product search add-on tool. Anyhoo, check it out and see what you think.
