In other cases, it sounds like they're just really optimistic that there are a lot of people out there that would be great to connect to, and how would you know if you don't look. Which I guess says something good about their opinion of strangers.
I'm in a state of "open to experience, but not looking". I work a 9-5(12 hours if you count wake up and commutes) with one girlfriend, and plenty of video games. Don't have alot of time to be "looking" for other people, lol.
I think it depends on your state of mind or area of life you're in.
