To make a simple analogy: If blogs are journals, tumblelogs are scrapbooks.
You can also look at tumblelogs as slightly more structured blogs that make it easier, faster, and more fun to post and share stuff you find or create.
You can find more information on Wikipedia.
Tumblr is your friendly, free, and terrifically easy tool for creating tumblelogs.
It’s totally different. That’s why we built it, and why we love it so much.
Blogs are great, but they can be a lot of work. And they’re really built to handle longer-form text posts. Tumblelogs, on the other hand, let you easily and quickly post and share anything you find or create.
