iPad: While most of the time you want to find exactly what you're looking for online as quickly as possible, sometimes it's interesting to randomise that experience a little. Futureful is an iPad app and browser that does just that.
Futureful works a little like StumbleUpon. You enter in a keyword or two, and Futureful shows you an article that fits that criteria. From there, Futureful tries to pick out articles that will be interesting to you. You can add tags, delete them, or just completely start over on a random topic. Futureful takes a little while to get used to how it works, but if you're a fan of StumbleUpon's randomness, it's worth checking out.
