I've Seen The Future Of Mashups, And Its Name Is PizzaShare
Seriously though, there are plenty of services on the web and on mobile devices that you could use to find a decent pizza place if you’re ever somewhere where neither you or anyone you know can tell you which one’s “the best” (Yelp leaps to mind). Also, the downside of crowdsourcing is that you have to at least try to prevent gaming; PizzaShare lets you vote (share) on a pizza place as much as you wish.
Creator Mike Mueller says he’s going to keep adding new features to PizzaShare, like geo-location, tagging, microblogs for each pizzeria, a recommendation tool, etc.
My advice? Don’t give up on your day job just yet (but keep building stuff).
You can follow Mueller’s PizzaShare blog here, it’s about pizza mostly.
