tumblelog

A tumblelog 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, this format is frequently used to share the author's creations, discoveries, or experiences without providing a commentary.
The term "tumblelog" was coined by Why the lucky stiff in a blog post on April 12th, 2005, while describing Anarchaia.
