100 email list unsubscriptions is a good thing

Since sending last week's this week at JDHQ, my email subscriber numbers have gone down by about 100.

I see this as a positive. What's the point having a couple of thousand people on an email list if none of them actually care what you're writing? What would be the benefit in trying to widen this audience by … what, just writing more generically? Writing less about the stuff that I'm actually doing and more about stuff that might 'drive engagement'?

90 engaged people are far more interesting to me than 100 who just never bothered to click 'unsubscribe'.
