Looks like I am either late to the party or early depending upon how your look at it. I just saw the GeekBrief.tv episode that talked about Jot.Com and I went to check it out and jot.com has been acquired by none other than Google. There is an section where you can add your e-mail address so that they can send you a message when it too has been assimilated, did I say that. I meant incorporated into the Google Borg…. There I go again.
Anyway the site was a good one for helping you take down quick notes and messages from anywhere. I unfortunately do not know how it actually works because I was late to the party. But you can go and sign up to be alerted to the rebirth of Jot.com.
