Sarah Milstein, co-author of The Twitter Book, offers some good tips for businesses looking to leverage Twitter as a tool for better customer relations.
We don’t do much leveraging of Twitter here at Portfolio, but we do occasionally gab. I’m on there myself, @davidmoldawer. Don’t expect any profound publishing wisdom, though…
Our own book in this space, Twitterville by Shel Israel, is due out in September, but you can pre-order it now.

Thanks for posting about us, David.
Looking forward to reading Shel’s book in the fall.
