Academic Milestones

I noticed today that one of my publications has been cited in two papers (by the same author). The papers were written in 2003, and the author gets the journal wrong in both cases (or I've got it wrong, but I don't think so).

I was aware of one of these papers, or a paper on the same topic, a while ago, so perhaps I already knew this. But today it came as news to me.

It's a milestone to me regardless.
