"A tumblelog (or tlog) is a variation of a blog that favors short-form, mixed-media posts over the longer editorial posts frequently associated with blogging. Common post formats found on tumblelogs include links, photos, quotes, dialogues, and video. Unlike blogs, tumblelogs are frequently used to share the author's creations, discoveries, or experiences while providing little or no commentary... really just a way to quickly publish the "stuff" that you run across every day on the web" via Wikipedia
