I am a senior professional in my mid 50s. I recently (last six months or so) had to set up a LinkedIn account and have around 50 or so contacts, all in my industry. A couple of days ago I saw one visitor to my page was a guy I was at school with. He is in a completely different industry and we have no reason to have overlapping contacts. We were good friends back in the early 90s but it's been decades since we were in touch. No shared social media contacts otherwise. Would LinkedIn have put my profile his way or has he been creepily checking my name for years and just got lucky now I have joined?
