Everybody is talking about how there needs to be a showcase application for microformats. Something that helps people understand the power of it.
There's also all of this talk of greasemonkey and ajax. Well, here is an awesome idea for all you geeks that want to save a lot of people a lot of time...
Do you know how many bands and venues enter their event/gig into 50 different websites? Do you know how much time this would save? Do you know how many people would then understand what microformats, reblg, etc can do? A lot.
What other real world problems could we solve immediately by applying some of this goodness?
