I am a big fan of the Zite app for the iPad. It searches the web for articles categorized by topics you select. In addition to general national and international news I have feeds for gardening, Vermont, brewing and social media. You can get stories about things that interest you quickly and from sources you might not know about. I opened the app today and two articles at the top, side by side, gave me a chuckle. That particular planet gets too much of a ribbing for the unfortunate double entendre of its name.
Both articles, by the way, were interesting.
