This episode, we take on wikis: when you should use them, and when you should try something else.

And we try on a new feature: the tip-off, where we alternate coming up with handy tips on a topic until one of us runs out. The result is our first 20-minute episode... which tells us we might want to review the rules. Maybe require each tip to be phrased as a limerick...
