I met Andrew Hyde at SXSWi this year. We exchanged business cards. His was a bit different as it had a drawn portriat of himself on one side and a very web 2.0 set of info on the other. i.e. his twitter username It was also a different size and shape than a normal business card.
Then, about a week later I get a nice hand-written card from Andrew…I good reminder of our meeting and his different, slightly traditional, method of networking is a perfect mix of new and old in my opinion.
