From their site: Use the Tumblr API to read Tumblr data or to write a Tumblr post. Unlike blogs, tumblelogs aren't designed like a newspaper column. If blogs are journals, tumblelogs are scrapbooks. 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, such as photos, videos, audio, quotes, and links, or text.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
