This site is kinda sorta like meetup but way better. I like it because you can suggest a meetup or get together or even virtual collaboration on anything and it doesn't have to be like a regular forever meetup. Want to take action on some kind of grassroots project - this is the perfect way to find other interested folks and to then be able to organize and collaborate with them. Or it can be something as simple as arranging a social dinner with neighbors, or coordinating elder care. I plan to use it to coordinate caring for my sick neighbor with my neighbors family/friends/other neighbors. So public or private coordination really... but more for public. I loved the site and it is evolving and I am hopeful it stays great.
