I'm not a user, so take my comments with a grain of salt. I think of this as something like an "intro to connection," a way for lonely people to bootstrap from zero friends to one or more. I'm very comfortable talking about personal stuff with pretty much anyone, but I definitely was not like that in my teens and twenties. It took me lots of experience and not a little therapy to get to the point where I'm comfortable. Perhaps this can be a shortcut for others.
