Do academics use Linkedin for anything? I inquire because a small, but not insignificant, number of people ask to join my network.

Their requests accumulate.

The auto-generated reminders become annoying.

I log into the site and expand my professional ties.

The process begins anew.

No other circumstances compel me to visit Linkedin. I suppose I could cancel my membership, but that seems like too much effort. Am I missing something?
