Many years ago, when I worked at Microsoft, I had a coworker and friend named Rangarathnam Gopu from Madras in India. Nice fellow, very talented software engineer. Over the years we lost touch; I heard vaguely through the grapevine that he had gone back to India.

A couple of months ago, a friend of mine in Denver posted a note on his blog mentioning that he was traveling to India and asking for various bits of advice. I had no counsel, but mentioned in the comments of his blog post that if he was in Madras, and if he met a fellow named Rangarathnam Gopu, it would be nice if he would send my fond regards.

Yesterday I got an email from Gopu. He had been Googling his own name, as we all occasionally do (well, maybe not the John Smiths among us) and one of the top hits was, you guessed it, my comment. So he tracked me down via the comment, dropped me a line, and now we’re back in touch. Amusingly enough, he got sick of software right around the same time I did. His second career choice? Writer.

It’s a small world, if someone indexes it for you.
