There are plenty of people who come, weigh-in and leave without attending the meeting. IMHO, that's wasting your money. The best part of WW is attending the meetings and getting tips and support from others (you get some really great ideas from the other members!). If you just come to weigh-in, why not just buy a diet book and a scale? It's a lot cheaper in the long run. But that's just my $0.02. If that works for you, then there's no reason to do something you don't want to do.
Personally, I enjoy going to the meetings. They are social in the sense that you are getting out and mixing with people that you share a common bond with and you can laugh at shared experiences and when you've had a success, people will congratulate you or encourage you if you're being challenged. I haven't made friends in the sense that I call them up and we go out and do girlfriend things, but there are people that I chat and am friendly with each week, and that's pleasant for me. I have observed others making good friendships at meetings and doing things together or working out together.
I think, too, that different meetings have different characteristics. Years ago, I used to go to a lunchtime meeting in a business district. The meeting was full of other people using their lunch hour for the meeting. The attitude was get in and get out and get back to work. I go to a Saturday morning meeting now and it's much more leisurely. A lot depends on the time you go and your leader. If you attend a meeting that you're not quite comfortable with, try another day or another leader and it may suit your style better.
I think you get out of the meetings what you put into them. If you go and you're friendly and you're looking for someone to bond with, there's no reason why you can't do that by being friendly and striking up a conversation. If you just want to sit in the back and listen to the meeting and go, you can do that, too. It's up to you.
