LinkedIn is a weird, weird place. 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 piece…
LinkedIn is going the MySpace way. Total crap “content”, endless amount of people that indeed just want “connect” without intro, reason or anything else than bumping their numbers. Weird thing, I found it pretty useful up to 2 years ago. I guess that’s when the influencers takeover and bullshit blogging began.
The last time (among many) that I accepted a generic, canned message request, I waited a week for the guy to say something to me. Nothing, and I dropped him.
One problem for LinkedIn is that they have not made themselves so obviously above-board that a suspicion like mine would be implausible.
