Facebook says: …you should only send friend requests to people you have a real-life connection to, like your friends, family, coworkers or classmates.
LinkedIn says: …the basic type of connection is a contact you know personally and who you trust on a professional level.
Twitter says: …”people you may know” are based on an algorithm that makes personalized suggestions for you.
I say: Befriend people on Facebook and connect to people on LinkedIn using the same rationale as Twitter.
A strong tie is someone who frequently and reciprocally communicates with you. These are who Facebook and LinkedIn refer in their descriptions. But, if you limit your online relations to strong ties, you’re saying fuck you to everyone else. I once said that. I later regretted it because what comes around goes around.
I don’t differentiate between Facebook and LinkedIn anymore. They’re basically the same platforms to me, merely showing different parts of our lives. If you use one over the other, feel free to invite me to be your connection or friend and I’ll gladly say yes.
