That link is not showing "12 new programming langauges" at all, the author explicitly states he is attempting to learn those 12 languages. I mean if you just quickly glance at it you'll see Erlang, Scheme, Scala, and Lua listed in your "new" languages.
A quick google found me 12 New Programming Languages. There's probably more, but i lost interest realizing there are probably way too many more.
Personally as I've worked a lot in real-time network games and systems I find Erlang to be a great language (although it can't be classed as a 'new' language as it has been used for many years and is battle tested on real world systems.
