@dansup many of these different social media’s (microblogs, personal photoblogs, personal video shares) have different circle of friends, acquaintances, random people you’d want to share them with.

One way to enable that is separate (external) account names, an other could be what (I think) Google+ did with its circles & what Insta kinda does with “close friends”.

I don’t know the best solution, but just wanted to add my thinking on the topic.
