It's written "Tcl", not "TCL". This has been true for at least 10 years, as the article nicely demonstrates.

Nitpicking aside, I agree that it's not real lively, but I don't think I'd call it 'dead' quite yet either, as there is still a fair amount of active development, and anything that widely used doesn't just up and go away from one day to the next. They even published a new Tcl book recently:-)
