Drinking coffee and listening to Scoble’s video on Twitter.
For future reference ( or never 
cos I don’t feel like installing any of these now):
There’s a desktop client for Twitter called Spaz. Downside: you need to download 9 megs of Adobe AIR beforehand.
Twitter.pbwiki.com lists a long list of Twitter apps.
Here’s a description how to set up TwitterVision as your Windows XP desktop.
If you enjoyed this article, please consider sharing it!
If you do try Spaz, please let me know what you think (good and bad) — I appreciate and respond to all feedback.
Thanks!
Hi – I think my favourite so far has got to be the TwitterBar Firefox add-in which lets you post straight from the address bar.
