Glad that you had that disclaimer Jenn!!! I wouldn't know what to think otherwise. :shock:
I would suggest sticking to one particular style when starting out, and depending on your motivation/time/money choose one or more dances to learn. For the longer version, comments on the article by Jim, to read what I started out with, and just enjoy my normal ranting read below...
The article:
Jim talks about swing being the easiest dance to learn and I actually learnt swing first, but that's because of Ithaca being what it is!!!

ECS is a lively dance, and the great deal of time spent in open position could make it easier for people to pick up, but ECS is just awful if one does not know leading/following and the 101 other things that give life to dancing a dance!!!
I suggest an even simpler dance for Jim, which came to mind as soon as I read the article: contra! I might be missing something, but after doing the contras that I have done I feel that it is a lively dance and just about patterns, and that should suit Jim just fine.
And, perhaps Jim's article would be pursuasive to some people who are intimidated by dance, and get them started, but saying dances are just steps is like saying that food is mere sustenance. We need the variety to get the various nutrients what our body needs. Both are true, but there is a lot more to both then steps for dance and sustenance for food.
What to start learning:
I always say start with something that is of interest to you. Is it a style such as street latin/country/swing/ballroom/folk, or is it a particular dance? Then the next question is how much time/money do you have to spend on it? Those sort of questions help a person figure out where to start...You need the motivation and know that you will be able to follow through when you feel its tough.
If you are interested in a particular style then taking a survey class would provide direction as to whether you have an inclination to a particular dance. I've seen ballroom, latin, and folk survey dance classes offered, but country is not popular where I am. Haven't seen swing survey classes, and am not quite sure how one would do that.
For a person just starting out in dance taking dramatically different dance styles can be really confusing. Learning more then one dance is easier if they are a similar style and also is cross-learning. For instance, cuban/latin/hip motion is common to all latin dances.
