Yay, I freakin' love languages!
Right now I'm trying to learn Spanish and French. I met a Frenchman on meetup.com and I meet with him on the second Thursday of the month (that's this week - yay!). There are supposed to be other people in the group, but the first meetup there was also an 8th grade girl. The last time it was just the Frenchman and me.
I took 3 semesters of Spanish in college for the heck of it.
I would also really like to learn Japanese and Chinese, but especially Japanese, because I took culture courses about China and Japan and really enjoyed them. I took a free Chinese course in college but stopped going halfway through because the Taiwanese teacher was using songs and picture books to teach, which is how she taught her kids.
I also significantly dabbled in Latin and Esperanto (an artificial language with a small but enthusiastic following) but stopped learning because I didn't really know how I could use them. Spanish, French, Japanese and Chinese are all used where I live (they all have groups on meetup.com) so I know I have places to use them. I might try Latin and Eo again sometime but I want to learn more useful languages first.
tl;dr
What I plan to learn now:
Spanish
French
Japanese (not so much right now, though) - I suggest
this video series for people who want to dabble in nihongo
What I would like to learn someday:
Chinese
Maybe German; I'm German on both my mom and dad's sides of the family
Maybe Italian
I've been thinking recently I might want to try ASL (American Sign Language)
I have several books on various languages that I wanted to study at one time or another.
