Feedly, one of the most popular alternatives to the defunct Google Reader, has just announced that the Feedly API is now open to all developers. Last month, Feedly kicked off a paid subscription service, Feedly Pro, offering the first 5,000 subscribers a lifetime subscription for $99.99. Feedly raised almost $500,000 within the first eight hours.
PubSubHubbub has become the standard protocol for real-time RSS and Atom feed subscription and delivery. But not everybody wants to host their own PubSubHubbub hub in the same way that hardly anybody hosts their own website, and why cloud services in general have become so popular. Guzzle Ayup has entered the market to offer a hosted PubSubHubbub hub service.
