That was big news at the time, mainly because of the cutesy "hobbit" nickname. As the article you quote makes clear, scientists still disagree over whether it was really a distinct species or simply some people with growth defects. 12,000 years ago is also incredibly recent for another hominid species to have been running around - Neanderthals, by contrast, disappeared about 30,000 years ago, which is itself pretty recent by the standards of human evolution.
