There are several options to add Twitter to Google Wave. I have tried both and they both work fine.
The main point I guess is for Google Wave to become a one stop shop. You will read emails, chat, video conference, do group meeting, send invitations to events, tweets etc…all from Google wave.
A very simple way to tweet from Google wave is:
Google Wave
Use TwitterGadget in Google Wave
1. Login to your Google Wave account
2. Select ‘New Wave‘
3. Select the ‘Add Gadget by URL‘ icon 
4. For gadget URL, enter: http://www.twittergadget.com/gadget.xml
5. Click ‘Add‘ and you are done!
The second option is to add a participant to your Wave. (tweety-wave@appspot.com). It is that simple. This guy shows it with screenshots: http://daggle.com/add-twitter-google-wave-1424
Have you try tweeting from Google Wave? Is it something that you consider doing?
