In recent months, some friends of mine have complained about people who attend lindy exchanges without ever knowing the lindy basics. They find this frustrating and rather annoying. One gal, for example, didn't know how to dance lindy but she tagged along during a lindy exchange weekend anyway. She did this because she knew there'd be some blues dancing as well. I've heard a few other folks voice the opposite opinion, though. They say that everyone should feel free to come, and that people need to lighten up. "As long as you're having fun," they say, "that's what matters." So what do you think? What is your opinion on this matter?
