Tips on how to use Twitter well

I've started a series of AudioBoos on "How to use Twitter well".

Every Monday I record a short audio to help people get the most from their Twitter.

I was inspired by the work of Paul Boag of Boagworld on Audioboo. Every Monday he delivers advice on some aspect of websites - how to design your website, how to interpret Google Analytics and so on.  He has a big following.  I find him helpful & interesting.

So I decided to follow his example for Twitter.

TwitterTips:

(1) Use Twitter Lists

(2) Use "Favourites"

I hope you find them helpful & interesting.  As these are the start of a series I hope to sustain for many weeks, I'd be grateful for some feedback.

How could I improve the Audioboos?

What topics would you most like me to address?
