Social networks help us to make our relationships stronger and ongoing.
But if you send friend requests to someone who you’ve never met before or don’t know well, your social graph may get noise. I had learned it from my first social network experience back in 2004-2005 with mixi and MySpace.
On Twitter, that kinds of connections work somehow because they invented the follow concept which means one way connection. Path‘s concept was also great. They tried to solve it with the 50 friends limit but I think it doesn’t work so far. There is no clear guideline to define who is a friend and who is not.
I believe we can’t make that kinds of decisions because we don’t do it in our real life. We need an algorithm.
