jQuery got the Nickelback treatment. Except I really did enjoy using jQuery, and only moved on because "the industry" was and I didn't want to be left behind.

Looking back now, we all were lead down a path of needless complexity. Even thought I'd never use jQuery or jQueryUI professionally now, I still have a voice in the back of my mind that will pop up every now and then to say "well, if it's not gonna be complex or long-lived..." when something calls for a quick UI.

I feel this way about Bootstrap and maybe now am old enough that I don't care if it upsets other developers.
