You have a really extensive internet presence, maybe more than you imagined. I've run into you in a couple places. I also remember being surprised reading your notes for the first time since you'd also done research on compton cameras, which was what I did for my undergraduate thesis (though I haven't thought about them since). The internet is weird. For every person that contacts you, there's 100 that silently lurk

I suppose you're right, it's hard to reckon our own presence in this semi-permanent digital space and then to consider how many pairs of eyes have seen our writings and postings and whatnot. I appreciate you taking the time to comment here, @saddleblasters :]
