textpattern was all the rave couple of years ago with easy to use templating Designers were free to achieve various looks and designs with html and no php when wordpress was not know for it flexibility beyond blogging platform. Those were early days of wordpress when it was first ported from b2. since than thanks to open source wp community wordpress and many other far eclipsed textpattern and those benefits that text pattern initially offered. Many will tell you chose a cms per project basis as many are good at one thing while not at other but i will say that with joomla and wordpress and their most valuable asset their ecosistem of devs and plugins you will be hard pressed to find a typensite that you cannot build with these top 2 free cms platforms...
sorry for typos hate typing on my pad
