The whole polyglot programmer thing is totally weird to me. Why would you not be a polyglot programmer? And why are we celebrating it as if it was something special?
Maybe it's a reaction against single language / framework conferences? There seem to be quite a few of those: Laracon (for Laravel), DjangoCon, PyCon, EuroPython, etc. Maybe it's good to have a technical conference covering multiple languages, especially for people who don't have time or budget to attend all the different language conferences?
[Personally I can see value in both approaches to conferences, though.]
