Not really keen to join more sites, and definitely not keen to have more work.
Anyone here find it useful, and why?
I check in there about once a week to see if there's anything useful. I only do this because a number of the more mature (to be polite) folks I work with use it rather than Twitter, Facebook, Instagram and a host of other things that are more focused on the younger set. LinkedIn has been attempting to become a central clearing house for business contacts for years, and (in my opinion) doing a very poor job of it. I rarely get anything out of LinkedIn other than occasionally long lost friends will find me because "Beau Vrolyk" is such an odd name. The same thing is true of Google+ and a number of other places like this, where I am also a member for the same reason. They are all chasing the really successful social networking sites and loosing ground.
Often someone new to LinkedIn will not "un-check" the box on letting them have access to their address book, and fail to un-check the box that says it's OK to tell everyone that this person has just joined LinkedIn. I believe this may be the source of most of your "invitations", which are often entirely unknown to the person who is supposedly "inviting" you.
