The success of online networking sites is intriguing to me. Facebook, LinkedIn, Plaxo; I've joined them all and encouraged my friends and family to do the same.
But I think the process is clumsier than it needs to be.
Let's say you meet someone interesting at a business meeting. You have a good, spirited conversation and exchange business cards. When you get back from your trip, you decide to look your new friend up in Facebook. You send an invite.
Now maybe he'll remember you. Maybe he won't. Maybe he'll accept your invitation. Maybe not.
The fact that you stood together, had a conversation and exchanged business cards is all useful data. Maybe someday soon your networking sites will know instantly who you met, how you interacted and the likelyhood that you'll meet again in the future.
Perhaps you'll be able to simply logon to your Facebook account and you'll see that you are already 'Friends'
