Warning: nerd at work. The question may be ambiguous. To highlight: compare "what's the oldest software you still use today" to "what's the oldest software you use today". The first one refers to software you have been using over a longish(?) period and the second to software that may be old that you are using even though you may have only begun using it. I hope my pedantry (pedanticism?) isn't too inane...

I hope my pedantry (pedanticism?) isn't too inane...

Or, you surreptitiously hope it's much too inane, much as people do with puns. What should we call those who secretly love pedantry? "Pedantophiles?" Oh what a difference one syllable makes!

I think that would be someone who secretly loves pedants, which isn't quite the same thing as secretly loving pedantry.

Am I doing this right?

[stcredzero]

I don't know. I got downvoted, so apparently I'm doing it right!

Actually, I like your sense of humour.
