> Here in Scotland I've met more Klingon speakers than Esperantists!

I wonder how many of those "Klingon speakers" can actually have a ten-minute dialog on a random topic.

The remainder of the article can be summarized as "Esperanto is not perfect" which I fully agree with. And it has a lot of irregularities, too! But still, ten or hundred times less than an average natural language. Which makes it so easy to learn.
