how do you use linkedin?
 

actually what is it for?
I just register, put my cv there and that's it.
People add me and i add them.

Is there more to it? Is it really a channel for finding jobs?

I try messaging people but no one wants to make friends with me.

Making friends is quite hard these days.

if u got nothing to offer, ppl wun talk to u.

yes, i noticed that applies to everything these days outside of work too. People make friends these days because others have something they want.
