|Feedly, the RSS app that climbed to fame after Google Reader shut its doors, is opening its API to other developers. The move, which brings Feedly closer to Google Reader in terms of being a platform rather than an RSS reading app, will allow for third-party developers to access its API and use Feedly's servers as a backbone for their own apps.
Fifty developers have been involved with the design and construction of the API, according to a Feedly blog post, with the final product being not only a feed-serving platform, but also provides a "powerful personalization graph" that carries categories, feeds, topics, tags, mixes, and other "higher-level concepts" for content consumption. This personalization will allow for a user to define aspects one one app, with the same settings and details spreading across multiple other apps and platforms.
Feedly had a meteoric rise since the shutdown of Google Reader. After the initial closure announcement, it added 500,000 users to the service within 48 hours, despite competition from other services such as Digg. Aside from a free service, Feedly offers a "Pro" option with search, Evernote integration and extra customer support for $5 per month or $45 per year.
