I've been experimenting with Paper.li, a free service that aggregates links shared via Facebook and Twitter and publishes it in a newspaper-like format. With Twitter, you can have this online newspaper created by using your Twitter feed, the feed from a hashtag, or from a list you've created in Twitter.

Using my own Twitter feed seems a little self-promoting and wildly varied as I follow 7000+ people. My global list consists of 160+ Twitterstreams of high quality sources, and thus this particular Paper.li newspaper tends to be a decent read each day.
