Sid, great write-up. I am very excited that there is a product that is designed around the sharing of links with friends -- especially solving the "issue" of me sending out zillions of emails to all of my friends every day. (they all definitely appreciate Mento <g>) Just posted to my blog about them too @ http://webpoet.wordpress.com/2008/05/12/its-ref...
I do not see why this app would be considered to be bullying when they (Google) have so many other free apps that directly compete with a bunch of other (non-37 signals) companies. What is so special about this particular app??
