Absolutely yes.
Tailwheel differences training opens up a lot of very interesting aeroplanes that you'd otherwise not get to fly (I can't speak for the Tiger Moth, never having flown one, but am a definite fan of the Chipmunk, amongst others), and also many of the cheaper aeroplanes to do fun flying in are taildraggers. Plus, it introduces handling skills that will benefit you in all of your flying.
I also agree - the title could have been a bit more informative. Mind you, it's a common sin.
