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.
