Esperantists are smug as fuck

Smug bastards. Seriously your little shitty conlang isn't the epitome of efficiency or perfection or logic. Do everyone a favor and learn a REAL language, a language spoken by more than twenty people. While you converse awkwardly with your neckbearded fellow "esperantists" in an Esperanto convention somewhere in Lapland, real men are fucking their hot Italian girlfriends who were charmed by their Italian skills.

Esperanto is a dogshit language.

It's really only going to work well if you already speak a western language.  Eurolangs show tense through conjugation, and number through declination.  That's not true of ALL languages.  Some use verbs to show deference -- there are different words for eating if you are high rank than if you are low rank. 

Personally if I were to make my own interlang, I'd try to make an isolating language.  Everything would be described by adding particles.  I'd try to find the most commonly used word for everything based on the population of speakers, not based on one language.
