Publr.com is a free blogging service with a few innovative features. It allows posts of various types, including your typical text, but also including maps, videos, chat transcripts, and links. Its site has a pretty good typical web interface for such things, and there are both first-party and third-party applications to use to post. Those third-party applications use the Publr API.
When the Netflix API turns three in October, it will also be making some big changes. With a focus on the quickly growing streaming service, Netflix will remove access to its DVD-related API calls. That means any websites or mobile apps that help organize your DVD queue will switch to only providing results that are available on its Netflix Instant streaming service.
