1) List something or tweak up an existing listing and “clone” it to make it new.
2) Tweet about your listing and tweet about something “interesting” that you read, or learned, or another seller’s items that you admire.
3) In our ongoing attempts to get a really good handle on Twitter I would like to introduce you to another Twitter application
http://www.twaitter.com. There is another similar but very busy screen and more difficult menu
http://www.tweetlater.com/alerts.
Twaitter takes you through a very simple process of being able to scheduale a Twitter message for later. The beauty of this is that you can list or refresh several listings at once but space the tweets out during the day . the value in this is that you will likely have higher views and more interest in followers if your tweets are spaced rather than piled up 3 consecutively. Give it a try it is fun.
