Name cards

While clearing through my stuff, I realized that I have accumulated thousands of name cards over the years - 2 case holders, over 10 folders and many other piles from different countries, different industries and different occasions, both from work, trade fairs, functions, or travel. Some were vendors, clients, acquantances, conference participants, and these contacts used to be important assets. Now that I'm out of the "industries", those cards became irrelevant. I got rid of all of them saved a handful - someone I bumped into on the bus and we chatted throughout the 4 hour journey, the trek organizer in Sikkim, ... a few personal contacts that I may find useful in future.
