I draw your attention to the tag connections.
Ten questions (at the moment). No usage guidance or wiki description.
About half of the questions are about LinkedIn connections. The rest are about network connections, Google+ connections, and a CW question for how to diagnose "when and why a website is down".
This would seem to be a meta tag. It has no context without other tags; it means different things to different people. Its primary usage (LinkedIn connections) seems to be adequately covered by using linkedin.
I think this tag should be burninated. Thoughts?
