Feedly is a service that's risen in popularity recently for the most part because the much-loved RSS service Google Reader is coming to close on July 1, but the company is definitely doing its best to make a space for itself as something more than just an alternative. Today, Feedly released the Feedly Cloud, which not only creates a standalone web-based RSS reader app, but also hooks all of your feeds into the cloud, which developers can then hook their own APIs into for various purposes. Just like Google Reader's API, the idea is to allow Feedly's work to power other readers, and in fact the service is connecting into IFTTT right away at launch, and opening up other options for future apps and tools.
This also means that Feedly is available right inside your web browser (previously, the app required a plugin or extension in your browser to work correctly), and can be pulled up from anywhere. Personally, Feedly has become my reader of choice, partly because it works so similarly to Google's service, and partly because it's so easy to migrate from one service to the other.
If you use Google Reader and haven't yet chosen a new service, you're running out of time, as Google is finally shutting everything down on July 1. Feedly is the best alternative I've seen so far, and this move to the cloud shows that the company is very interested in not only grabbing Google's refugees, but keeping their patronage for as long as possible.
