Now, Tumblr has made is easy for users to add attribution metadata to posts just as they would tags and other information. This is great for users who want to credit where they found an interesting photo, quote or article, but this feature is a huge benefit to publishers. As we mentioned earlier this summer, many popular publishers – including Newsweek, Huffington Post and The New Yorker – have flocked to Tumblr to share content in a new way. With this new attribution feature, they can rest assured that their content will be properly attributed as it is shared throughout the community.
