Twitter, Tweetdeck and Simplicity

The usability of a website is relative to the audience that it was designed for. A website that is designed well for its primary audience will not necessarily provide a great user experience for everyone that tries to use it. It’s important to identify your target user if you’re going to make a site that works well for the right people.
