Why?

John's posted about the vagaries of global interest in his blog a couple times (I don't know the specific post).

And I've looked at my stats occasionally.

But I just have to ask: Why is this post on my birthday last year so popular?  Just to set a benchmark, it is presently at 535 hits.

The next closest is one from a chain of blogs for scientists to talk about their blogs and their take on science in science fiction.  It got cross linked for the chain, but I can't figure out why one that just talks abotu my birthday gets so much interest.

Is it the picture of maple syrup served in a shot glass?

Is it the link to the Anchor Steam bicycle jersey?

Or is it the picture of Jennifer's bike with petunias in the front basket?

Please tell me, because I'd like to know.  Maybe I can duplicate the interest.  Any maybe I could break into double digits of followers.
