> Front-end engineers are invariably the most important and skillful, and backend engineers really aren't valuable.

Heh, that's interesting. I didn't see a whole lot of that on Twitter (though I kinda see what you mean), but I did know a senior engineer that referred to front-end engineers as "finger-painters".

I think both camps probably kinda looks down on the other a bit. (But I guess the frontend camp is louder on Twitter?)
