The Productive Exchange Of Ideas

Another quicky, another one where it'd be nice to hear from y'all:

All of this is pointless and stupid unless it actually gets used in games. So let's hear about it:

1. What's something you've read on somebody's gameblog that you actually used in a game?

2. And how did it go?

If it's something I wrote, I'd love to hear about it here, for playtesting reasons if for no other, but I'd like to hear about other people, too, and I'm sure everybody reading would, too...

Oh and P.S.
If you've used someone's idea in a game, tell them, too. I'm sure they'd be jazzed to hear about it, and how it went.
