There is something missing.
Personally I have a Linkedin, Goodreads, Pinterest, and two Facebook and Twitter accounts.
I meet a lot of people that I will add too one social media account or another.
If only there was an acquaintance app. New people you meet would first go into that account then if there is an interest they would work their way up to the main account. I am describing a purgatory account to prevent a massive dumping of friends and followers after forgetting who they these people are.
Would it solve anything?
