There's always people wanting to add me, but then they mostly don't introduce themselves. Even half of the recruiters who add me don't do an intro. How is that networking?
The articles seem pretty low quality. Sorry to say it, but a lot of them seem to be written as a form of homework, as in "you should write something to be seen". There's rarely any insightful comments on news pieces either.
And then there's Oleg. Doing a parody of him is basically the only form of humour on LinkedIn. Do you agree?
The endorsements system is messed up. My 6th grade teacher endorsed me for "derivatives" and "investment". That's not quite the same as a colleague or a manager, is it? But you won't know unless you check all those links.
The one thing it's good for is as a replacement for a rolodex. No need to have business cards anymore, you have LinkedIn.
