I don't know what's better, really...

I mean

More responses than plurks seems lurky

But plurks than responses seems lonely

somewhere between a 1/20 and 1/5 ratio seem best to me, just looking around. within those bounds i'd say its fair game

Wow, I'm dangerously close to the 1/20

but plurk itself says to plurk less

Huh, yeah, but I get locked for "spamming" when I try to correct my EGREGIOUS TYPOOOOS
