Those meetup groups sound like someone wanting to sell me something - so I'm not joining
I don't know about NYC but the bait & switch on MeetUp happens so much, I don't bother with new groups anymore. I've started MeetUps where the only people who came were people only looking to make a buck. Are there established, active groups you could join on MeetUp? If you are looking to promote a product/service, I'd check out some of the business networking groups first.
Meeting time/location might have something to do with it as well? I live in Colonie. I'm not going anywhere near the northway from 4-6pm
I'd say look for established activity groups - or try something new - hiking, scuba? I need a dive buddy!! If you want to learn scuba google out RogScuba or Seguins. Perhaps a Toastmasters group? I've been a member for a year now. Public speaking can actually be fun! Maybe sign up at a fitness studio focusing on group training (I know a couple) or a Crossfit gym? There's the Albany Running Exchange if that's your thing.
Find some Albany folks on Twitter & see what they're up to? Maybe checkout AllOverAlbany too.
