Anytime Lojban comes up I recommend taking a look at linguist Arika Okrent's book "Into the Land of Invented Languages". She learns several conlangs (constructed languages) during the book and has several chapters devoted to the history and her learning of Lojban and some of its pitfalls (some things take a lot of words to say). There's a reason why natural languages have so much ambiguity, so you don't have to write a novel to have a basic conversation. If you go to wikitongues on YouTube you'll see a prominent community member who can only read it and can't speak it...it isn't easy.

Edit: Lojban is ambiguous with how something is said, so when a speaker says something you should never misinterpret the words, but the meaning could be misinterpreted as I understand it. I'm no expert, but would love to see something like this take off.
