Earlier quoted context omitted.
As someone also with dyslexia, I thought it was pretty good. Yes it is not that extreme but that is the point of the piece I think.
Yes. It's just my interpretation of something I heard.
Sorry to be uncharitable, but here is how you could've written a more honest introduction:
I heard a friend with dyslexia say that letters just jump around for her. Without asking for details, this reminded me that I had a hammer called JavaScript, and this looked like a nail to pound. So I wrote some quick code with made-up parameters and copied info from Wikipedia for cachet. I didn't bother to get any further feedback from dyslexics about this, so it is purely my folk-interpretation of a condition I don't really know about. I then uploaded it to HN to get some feedback, but I still didn't bother explaining what I did or why.
