This is pretty much exactly what I was going to say, but I wasn't about to do it so politely. Who hasn't had that boss who thinks that because he once worked as a trainer in a group that did Java work and puzzled out god awful VBScript and perl scripts while creating an abomination of a MySQL database where everything is a string, but we can't change anything because hey, it works (for some values of "work").
In other words, until you've supported (and god help you had to modify) the hoary abominations cultivated by these "self-trained" deciples of the Elder Gods, you really haven't any cause think that the bitterness directed at these "teach yerself to code" websites as anything more than the the resigned realization that now there are even more imbeciles devoted to ruining your life that it is.
TL;DR: If you're to goddamned stupid to come to the realization that your abortion of a VBScript ASP classic "website" is slow because your're executing a query in a tight loop based on an ID you retrieved from a previous query that you could have trivially retrieved all at once in a single query then maybe, just maybe, you're too goddamned stupid to be programming. Furthermore, when you refuse to acknowledge that that very same website does absolutely no validation on input and it's breaking the bloody fucking things you wanted ME to develop because "it works", but if I forget to validate some obscure edge case you jump down my throat... then maybe you're just a douche bag as well.
P.S. Sorry, got a little ranty there... wish I'd submitted some of that shit to The Daily WTF.
