It appears that you have to be careful about setting your privacy settings to "Shared-profile owners and followers." What I'm seeing that actually means is that people have to be members on the site, and they have to be followers, to be able to see your profile, play your songs, etc. With this setting, you can't get followers because they can't find you to follow you. I would think that label needs to be the one marked "Most Private--followers only." But, it needs to have a way to be found so members can get new followers. As it stands, it would seem they have to reset their privacy settings to something more open every time someone wants to be added to their followers list. Am I missing something? It seems to me that this is the least "shared" profile setting possible. So, I don't understand why it says, "Shared." I had a new member use this setting, and nobody can see her or even search for her profile. If it wasn't for me having so few members, I would not have caught the issue. And she probably wonders why nobody's commenting on her profile.
If you don't want the general public to be able to see your profile, then you should change the setting to "Private-profile owners only." That will mean that only members of the site can see that you're here. I would mark that one as "Semi-Private--Members only." I don't think people understand what "profile owners" means, but they would generalize and understand, "members only" without regard to quota types which they don't understand anyways.
But if you want to show up on the front page information to the public, then set it back to the default "Global - anyone." I would change this description to "Public--anyone."
Just my thoughts for whatever they are or aren't worth.
