Only now, years later, do I discover that tons of busy important professionals have been pouring on to LinkedIn (which seems to be the busy important professional’s social networking site of choice, probably because you can’t buy each other gifts on it or play virtual Scrabble or join groups called “If 100,000 people join, my wife will let me name my second child Spiderpig”). And some of them want to “link” to me. Leave aside the question of why, and I get emails inviting me to click the link so we can all be busy important professionals with friends. Sorry, contacts.
