Waggable: "Will you be my friend?"

Overheard at a party (I was drinking so the quote below is a paraphrase), a victim of the LinkedIn effect says:

This guy meets with me, and he says, "I figure I need to build more contacts." It felt like he was saying "I have five friends, and I optimally have room for seven. Will you be my friend?" I guess some people just work that way.
