Twitter Advice from Business Week's Arik Hesseldahl

Here's some more Twitter advice from Arik Hesseldahl, Business Week senior technology writer and columnist:

1. Twitter from your iPhone or Blackberry, but do so using an application like Twitterific, and not via SMS, as the SMS messages can give you a case of bill-shock.

2. Try Twitpic.com for sending pictures that your Twitter friends -- and other people, it should be noted -- can see.
