Its basically a kind of Facebook for professionals, without all the general immaturity and rubbish on Facebook.
Its about establishing professional networks, and it helps connect you to people you may know in similar fields. You can set up or join various professional groups - like “engineers in Southern California” or “people who sell fruit” etc....
Yes, but it’s almost as ego-centric as Facebook, only in a “professional” guise. It’s a business ego trip.
Everyone gets to blow their own horn and brag about their “strengths”, and have them supported or suggested by Linkedin “friends.”
Mostly, it’s to feed the user’s egos.
The actual networking results in a practical sense are small.
