Ok, I went wandering around some of Sarah's friends' sites just for fun. Sarah, please tell your cow-orker Andy that the UNIX program Talk is not the same thing as instant messaging. Shame on him! Instant messaging is what the UNIX command 'write' is all about. Or any other myriad commands that network admins have used since the dawn of time to announce to users the fact that the system is coming down NOW, so log off or lose everything and don't come whining to me because I warned you.

That said, being one degree of separation away from the guy who invented Talk way out-geeks me. But wait -- this means I am (Sarah, Andy, Andy's friend) three degrees of separation away from him! My geek rating just went up. Thanks. In return, tell him that I am one degree away from Vint Cerf. Which makes him three degrees away from him, etc. and we're back to being even, except that he got the bit about Talk wrong.....

Ok, I'm going to bed now, really.
