Twittering with friends seems to be the new "thing-to-do" on the web these days. Many bloggers are using it and it has even made its way into an episode of CSI! So what exactly is Twitter you ask? Twitter is an online web service that lets you post what you are doing - in 140 characters or less - in which those who are "following" can track what you're doing based on what you post. Bloggers sometimes also use Twitter to share URLs and to share quick thoughts on a variety of topics.

Now I said that Twitter was a web service right? Well the Twitter developers have released an API in which developers can use to create "Twitter clients" to be used outside the web browser.

Alan Le, from the company Vertigo, has utilized the Twitter API and designed a WPF Twitter client called Witty (Download Witty 0.1.5 / 986Kb) that extends the Twitter experience into Windows Vista. If you recall, WPF (Windows Presentation Foundation) is built in to Windows Vista.

Another awesome product from the Vertigo folks called Family.Show is a WPF app used in tracking family history and creating a family tree.

With Witty, I can quickly receive updates from people I am following as well as quickly post on what I'm doing (or any specific thought quickly I might have) quickly as the app nicely sits on my notification area of my taskbar.

To install Witty, just download the .zip file (above) and extract to a folder on your PC. Once the files are extracted, open the folder the files were extracted to and double click on Witty.exe.
