43Folders has a post with solution to “what was the name of the guy who was sitting next to me at our last meeting about …?” problem. Simple and effective.
Most people out there won’t remember names of other people from the first time. Especially when introduced to a bunch of people at once. Which is an often thing to have at business meetings. And, oh well, I am one of those people.
While I frequently had my memory failing me, I never had a problem of asking for the name again, or simply avoiding name altogether (eye contact and finger pointing are my favourite techniques). But not everybody is like me. And even me is not like me sometimes. So, the thing with meeting maps is nice to know about.
