Janice, I think this is a really fun idea, and one that Dave and I discussed before the site even launched (I told you all that we had tons of ideas!)
It isn't something that we can jump into right now, as we're pretty swamped with stuff, but I think it is worth looking into.
It would definitely motivate us if some of you started doing some, and entered them on your blogs. We can always move them into one central location easily enough! There's no way that Dave and I can make so many tutorials, and we don't want a feature that only has one or two items in it. BUT- if you all start making them, and they are good- we'll definitely look into ramping up the feature!
