There was a recent thread about keeping track of KITW lists and contacts (ensuring that you're keeping in touch with everyone that you need to keep in touch with).
I'm having a similar dilema. M&M suggest having 1 networking lunch each week. How do you decide who to invite for lunch? Ideally it would be great if I had a system that allowed me to group all of my networking contacts (thats the easy part - Outlook can do this) and then also track the last time that I have face to face interaction with that person (that's the hard part). Then I could simply sort by those that I've gone the longest stretch without seeing.
Does anyone have a system that they use for this?
