I subscribed to you yesterday, I think, when I saw that you had subscribed to me. Subscriptions assure that the subscriber will see the subscribee's public posts. Granting access assures that the person will see your protected posts, as well. For example, if you just want to see my public stuff (vid announcements), then subscribing is enough. If you want to see the primordial soup that is my brain, beyond vid announcements, then you need access. hee

(You probably knew that, but some friends didn't, so... Hi!!)
