shows people how LiveJournal works. Well, it's time to give him what he wants!
Take a look at how Diary-X, (an otherwise insignificant weblog) does their site tour, for example. Pretty spiffy, I think. We could use one too.
Multiple volunteers allowed on this project! You can do the site tour like Diary-X does with non-functional forms, etc. or you can use screenshots or images to add in things like arrows and text to point out places on a page, what they do, etc. Whatever works best for explaining the page in question.
