Hey, whatever works for you. There are many people who I’m friendly with, but I’m not friends with, and they can be useful to find out information about employment opportunities or other things like that. Whether or not you want to call it “corporate hustle poison” or networking, or just being friendly is up to you. If you refuse to be part of it, no skin off my back, but if someone wants to be part of it then that’s perfectly fine too. There’s nothing intrinsically wrong with LinkedIn, Facebook or almost any other social media platform. It’s really in how you use it.
