It would have been more intuitive and less work on their part to have "guess" and "forfeit" buttons.
It's the languages with very distinctive features that can be guessed quickly (assuming you have seen them before) e.g. cobol, erlang & also joke languages like intercal, brainfuck, chef etc.
pretty cool quiz, i definitely don't know hardly any of these...
Edit: ahh, it does work, but the first time I did it the red bar completely covered the forfeit link. Subsequent times it's been above and fine.
D for example... how are you suppose to get that one right?
edit: Oh never mind, this is just a shitty user experience. Sorry for the misunderstanding, folks.
Some language syntax are too similar (eg scheme and racket) so you need to know the libraries as well.
In the "Identify a Language Game" Game, this one loses. Sorry!
The external scripts should instead be loaded securely, or using the same protocol as the main page.
ps. I found a bug: Delphi is not a programming language, but Object Pascal is.
I will definitely consult this next time I find myself asking which language I should dabble with next.
Around 70% of the ones I got were languages I have never used, which seems kind of odd.
