I feel like digging up specific plurks and nitpicking on comments would be far more micro-managing than what was, mostly, an impression. I'm glad you don't share the feeling, actually, if you don't feel overloaded that's great.
The impression comes partially from rp plurks (and others) often being laments of how many tags there are pending, or most plurks of the game where you tag into things being marked as either late, or not late for once!, which would imply the lateness is a given. Perhaps it's taking silly commenting on having lots of things available too seriously. It's also partially from experience, with threads often being dropped and plots or ideas for CR taking very long to be executed, if ever. Not that RP isn't a two-way street, and if communication is suffering due to an (untrue) impression it makes sense other things wouldn't work out as well.
I apologize for coming across as wanting to dictate your rping, obviously you'll know better what you can and can't handle, and anyone's impression of your situation will never be fully accurate.
