Tumblr, free

Tumblr is a site that's growing wildly in popularity. It's a hybrid of blogging and tweeting, which allows you to upload quotes, high-res images, videos, music, photos, links and just about anything else to your page. Those following you can then "re-blog" your creations, or "love" them, which then puts your photos, tunes or vids on their tumblr sites for more to see. This app helps you update your page at the touch of a button.
