Spaw,

I may not have even been here before the upgrade you're talking about. I guess this is just something I failed to notice until relatively recently.

Maybe it's become more popular and much more frequent?

Or maybe, when I first became a more-or-less regular, it had only recently become less necessary to mark #100, so that the practice might have fallen out of common use for a while?

I really doubt that I could possibly be getting more perceptive in my old age. The opposite is much more likely...
