Am I the only one?

So I was reading a favorite blog (You should totally check her out. She's hilarious! )and she posted about Esperanto. I never even knew this existed. Where do you even learn it? They certainly aren't advertising Rosetta Stone in Esperanto. I just thought I was pretty educated...at least on the basics, but never once have I ever heard of this. Or Chisanbop? Really? Do people use this? Well, I'm not sure if I'll ever use it, but officially know how to count in Chisanbop (if that's even how you use the word). So I just thought I'd share. If you didn't know, now you do. :)
