Just had word from Seesmic that they have launched a new Twitter client, which runs as a native Windows application. You have to be on the beta list which is easy to join by visiting the Team Seesmic page. So far it is looking pretty good, although we still can’t figure out how to unfollow people, which means visits to the twitter home page are still necessary. It is an improvement over the Seesmic Desktop client though, and so we expect this will be a popular download.
