I suspect the answer to "Why was ___ excluded" in most of these cases is "accidental oversight".

>>"accidental oversight"

Which is just another word for "conspiracy."

Proof that HN has no sense of humor. :)

The same reason why I left out C and D in the mentions. Their name is too often used to mean something else. :/

What other meaning does "Perl" have?

The thing coming from a shelled mollusc? Haha, I am so unbelievably stupid. Thanks for the remark. I will try to fix it during the next days.

Just curious if you considered lumping in node/node.js in with JavaScript... I know it's a platform that uses JS, but it's gotten relatively popular.

I thought about it but left it out because I did not know what I should do with Rails, Django, JQuery etc. then. ;)

Just to let you know, perl is in now. ;)

Interestingly, Perl does make appearances in much of the word usage section. It's absence from the rest of the article is curious.
