One of Several "Must Have" Web Apps: Posterous

 The other 'must haves': 
1) Jott.com Email or SMS notes by SPEAKING the text. Jott transcribes 
your note and sends it. On a Blackberry, reply to emails by selecting 
'Reply with Jott' from the context menu 

2) Kwiry.com Send notes or pictures to kwiry.com and retrieve them on 
the web. Preface the note with 'p' to make it a private note. 
(Otherwise, it's there for the world to see.) 

3) xpenser.com Send expense information via email or SMS. Format like this: 
exp 73.45 Chevron 

4) getdropbox.com Upload stuff and allow friends/family to download 
the stuff. If you can actually get a beta account for getdropbox, play 
the lottery - you are very lucky.
