Linked in is simultaneously the most useful and useless social media platform.
On one hand, you can use it to get jobs, and keep a line of contact with former/present colleagues in a professional setting (as opposed to Facebook or remembering to write down their personal email address).
On the other hand, you have the feed, which is full of the most stupid, banal, and preformative shit you'll ever see on social media, because it's all in the name of advancing your career in this superficial society of ours.
I hate it, but it has its uses.
I'm surprised Snapchat is that popular. It's not something I hear about too much anymore.
