Yep. In various iterations.

When I was younger (13-14) I started playing around with VB5 completely organically to try to build an application that would manage photos (my father has a photography business).

I was discouraged against both the programming in VB (it's beginner stuff and you can't make anything good with it, was the basic message) as well as against building/finishing the image view/organization tool (at the time ACDSee was all the rage, and I was going for something of that nature).

Well, sadly, that was all I needed to hear to realize that I was going down the wrong path and if I wanted to get into programming I would have to wait until college.

Thankfully I found PHP (gasp) a few years later.

Variations of it. It could also be something as simple as "You don't know how do to XYZ in JavaScript?! It's like 101!" Either way - encouragement/mentoring is always good.

I've had it happen to me. My mentor was going over a perl program of mine, showing me some beginner mistakes, and I was making good progress in understanding where I went wrong. Then a friend wandered in, sat in the loungeroom, and started throwing out abuse at perl and how it was a stupid language etc. Focus completely broken, and no more progress was made, because this guy just had to abuse language X to a beginner learning it.

You must have missed "PHP: a fractal of failure" or the endless rounds of sniping whenever a university changes from teaching its Into to Comp Sci courses from <whatever> to Java.
