Tumblr recently launched a new feature based on their post tagging. They are experimenting with three topics, news, fashion and long reads. It’s an interesting idea. You essentially end up with a kind of curated blog edited by other bloggers. Tumblr assigns qualified people as editors for a certain tag, and they highlight the best stuff on tumblr.com/tagged/tagname.
Just like individual people and their blogs, you can follow curated tags as well as regular un-edited ones. I’ll be interested to see how Tumblr continues to evolve this into a more prominent part of their service. I think it will help them to further differentiate themselves from other self-publishing platforms as a more community driven site rather than a service that feels much more individual such as WordPress.
