One of the things people do on social networks is share links to things they like.
Take a look at any Facebook wall or Twitter stream and you're bound to see a ton of little URL-shortened links leading out to content somewhere else on the Web.
Trying to filter and absorb that information can be a real challenge. Separating the links from all the other chit-chat takes time.
Now there's an app for that. Flipboard is an iPad app that takes your Twitter and Facebook streams as a data source and presents the links in a newspaper-like interface-complete with simulated page turns.
