Found source for 1-minute refresh for Twitter...

Thanks to Charles Roop for this...

One of my worries over Twitter being useful as a weather bulletin dissemination tool was the fact that you don't see new bulletins unless you manually refresh the screen, which kinda forces you to sit there at the computer.

Thanks to Charles Roop for mentioning TweetDeck, which is an application you can use to see new posts by setting the application to refresh up to once every minute.

To download the application, go to http://tweetdeck.com.

(Thanks, Charles.)
