Seesmic Desktop so far has been the only program I have used (other than the Power Twitter extension for FireFox) for twitter and I enjoy it! It is a very easy-to-use program that users can figure out without beating up the computer. It lets you update your tweets without even going to the website. I enjoy using the program and I am sure others would too!

Twitter is by far a great site were members can post updates, ask each other questions and socialize with others.  It has a way were users can personalize there designs and just have fun. Users also have fun with hashtags, Follow Friday, voting and much more.
