I'm wondering what language I should focus on learning. I'm open to most languages that aren't too terribly complicated.
Ones I won't learn are German and Spanish, or Arabic. German because I'm already taking classes for it, Spanish because I don't want to learn a language everyone else is, that's no fun, and Arabic because the writing system will make my head explode.

I'm just wondering what language everyone thinks I should learn. Languages I've dabbled in are:
Finnish (very lightly)
Russian (somewhat more)
Swedish (some)
Norwegian (little, about as much as Russian)
Danish (hardly at all)
Icelandic (little)
French (some)
Korean (barely)
Japanese (little)

I'm sure there are other languages I shortly dabbled in because I was bored and curious.
Now, how I would like this formatted (if you'd like to, it'd make me happy, but you are the answerer :P )
Language
Why?
Diff on scale 1-10. 1 - hardest
Availability of learning mats. 1-10
Use in real life 1-10
And links to any sites or such that you know of, if you don't mind.

e.g.
German
Because it's the second most used language on the internet (include other reasons if you like)
7
8
6-7

http://en.wikibooks.org/wiki/German

Something like that. You don't have to use the template if you don't wish to, you could just write an explanation why I should learn this or that, like most top contributors do.
I know it's a lot, but I'd really appreciate it.
ALSO! Don't be shy to put more than one language.
