Tumblr is a free microblogging site where users quickly and easily post short snippets of text, quotes, photos, videos, links, music, or whatever else interests them in a rapid-fire fashion.
How does Tumblr Work?
Whenever users stumble across something they like online, they can click a “share on tumblr” bookmarklet to automatically post it to their blog. They can also publish new posts by emailing or texting them to tumblr. The result is a tumblelog: a microblog consisting of short, quick mixed-media posts.
