You might be using LinkedIn wrong, according to its founder

If you use LinkedIn, you've undoubtedly received invitations to connect with people you've never met or may never meet in your life.

The more you stay on the site and the more you gain prominence in your field, the more requests from strangers you'll get.

And while it could seem natural to decline a Facebook friend request from a stranger because you don't want to give them access to your personal information and photos, the dynamic on LinkedIn is much different.

You may think that because it's a social network for professionals, you should accept all invitations and see which of them stick.

It's the approach that Keith Ferrazzi, the author of "Never Eat Alone" and a management consultant to Fortune 100 companies, took for years. Not long ago, Ferrazzi wrote in the 2014 updated edition of his best-selling career guide that he had the privilege of meeting LinkedIn's founder, Reid Hoffman, and discussing the site with him.

"'You're doing it all wrong, Keith!' That is, in essence, what Reid Hoffman told me when I told him how I was using LinkedIn," Ferrazzi writes.

Here's the gist of what Hoffman told him, as written in "Never Eat Alone" (emphasis ours):

You don't need to do a deep analysis of every person who asks to connect with you, but if you'd feel awkward chatting with them or introducing them to someone in your network, decline — without a guilty conscience.

And if you want to use LinkedIn as it was intended, make "at least one quality introduction a month," Hoffman suggested in his 2012 book, "The Start-Up of You."
