How effective is "Meetup.com" in meeting people, in-person, who have common interests, compatible personality?

meetup.com is a great way to meet people in your area with similar interests. I think that you will find both single and coupled women joining. The biggest factor in the number of people or the type of people that join is your area. If you live in a more populated area where there are a lot of singles in your age range, then you will have a better chance. I think you should try it. worst case is you only lose $19. Good Luck.
