JQuery isn't a programming language, it's a Javascript library.
MySQL is a database of SQL, SQL is a query language.
HTML(5) is a markup language.
Javascript is 1 word (Not Java Script)
CSS is a style sheets, not a programming language.
MySQLi is a MySQL extension (that 'improves' it; hence the i) - and is only used in PHP, still, not a programming language.
The only TRUE programming language listed in that poll would be Java.
I suggest changing the thread title.. Sorry, I just had to point this out.
