Encourage all the schmoozing you can from your players. :3

1) Know your players. Small groups containing precisely zero dickheads are pretty easy to manage.
2) Keep secrets. You can always fix inconsistencies later if nobody knows they're there... ^^
3) Make sure that everybody is engaged in at least one strand of plot at most times
4) Allow players to approach the game from whatever angle they want to come at it from

I think that's basically what I'm doing in Wolf that's working well.

+5) Active OoC participation. The reason that I think this game is working is because you guys like it (hopefully :3), and if that's right, it's because I'm paying attention to the OoC and directly asking people what they want from this - whether they want to slow down or boom ahead.
