Robin Good: Snapguide is a new free iOS app which allows anyone to create a step-by-step visual guide on just about any topic. Guides can include text, images and video clips and everything can be authored directly on your iPhone but can be viewed on the web, tablets and phones. Finished guides can be easily shared on Facebook, Twitter, Pinterest and an integrated chat functionality lets you chat with people who share your interests. Examples: http://snapguide.com/guides/.
