Tcl/Tk is still used a lot. Tcl is still great for scripting applications and ships with many professional tools. Digital IC design very strongly depends on Tcl. Afterall, it was called "Tool control language" to script the design tools Ousterhout was developing. Tk is still the quickest way to create a simple UI which is also highly portable across operation systems. With tclkit you can even create self contained Tcl/Tk applications on the big platforms (Win/Mac/Linux).
