Under-hyped web apps

Here's a list from Lifehacker of the above.
One that looks very interesting is Jott which, apparently, allows you to talk to your computer about something you want to be reminded about and it will send you a text email. Have4 to try this.
EDIT: Just found when I went to try this today that it only seems to work in the USA in that you need to call a USA cell-phone number and then deliver your voice message to be transcripted.
I suppose you could use it from other countries too, but your phone-bill is likely to skyrocket.
