About "grant access," since we're all probably going to have to get used to that being its own designation now:
I rarely post anything that I would be uncomfortable having strangers read, but sometimes I do lock things because I want to keep them off of search engines or make sure that real life friends, family, and coworkers don't see them.
If I've granted you access, and you don't know me, it's nothing personal and I won't be insulted if you choose not to add me back. But, I'm here to talk to people, so I'd be thrilled if you do.
