So you think reducing n by 1 (or any other number - even a percentage) puts an upper bound on n? What exactly is this limit you're thinking of?

Anyway, I don't see the point in arguing semantics. I'd simply rather not have yet another section in which people post a mish-mash of on-topic and off-topic stuff... especially if it's construed as encouraging off-topic posting in PerlMonks. But that's just me. I don't speak for the site policy makers.

Golly, I didn't know it had been tried already!

Of course it's already been tried. How else could you have said

it limits the impact of OT threads on PM's 'core business'...
