I wish I would have started years ago. It's so great on so many levels. You get out, you meet people, you get exercise, there's often food provided, great music, and if you get tired, you can just sit and watch other people dance. If you invest the time to become competent, you will be in demand, and everyone who's serious about the dance will dance with you. You also get more comfortable touching other people and being close to them without all of the sexual overtones that occur at some dance clubs. This makes you a better dancer, because you become more sensitive to what the other person wants, to what they're doing, to how their body moves, to how they will respond to your energy, etc. It also really makes you empathize with people, because you can learn a lot about their personalities just by how they dance, or by how they talk about dancing. By dancing with them, you are having a non-verbal conversation, and after you've danced with someone a few times, you feel like you know them better, even if you haven't talked with them much.
I actually think that Argentine Tango isn't that unaccessible. While it's more difficult than most if not all of the other social dances, the concepts aren't so esoteric that they can't be grasped and applied with a little bit of determined effort.
Also, because it is challenging, there is a VERY strong community that nurtures its newbies with low-cost practica and relatively inexpensive lessons.
Here's a link to videos of around 100 Tango steps.
