If you're using Twitter, then you may have got bored reading the web page updates and downloaded a little desktop application or applet for keeping in touch. (I have).
One problem is that it's yet another application.
So here's an alternative for anyone using Outlook.
I stumbled across a little Twitter add-in that delivers twits directly into a folder in Outlook where you can read. reply etc. It even has statistics!
It's called OutTwit, you can find out more and download it from here.
