Firebase, real-time backend for web application development, originally launched a little over a year ago. Since its launch, Firebase has remained in beta while it continued to improve its service and build a customer base. Over the past year, Firebase has added features, functionality, and thousands of customers. Accordingly, Firebase has announced it is leaving its beta stages behind and publically launching as a full-fledged paid product.
Three months after its initial launch, much-talked-about data portability service Gnip has released version 2.0 of its API, as well as the first glimpse of a business model. As we covered back in March, Gnip's goal is to "connect Data Consumers to Data Publishers in a low-latency, highly-scalable standards-based way." Gnip is a sort of proxy that makes data from diverse Publishers--services like Delicious or Twitter, which create activity content--available in a unified format, and notifies Consumers--like FriendFeed or Plaxo--via a push interface when new data is available. The new version of the API adds full data delivery, XMPP support, and advanced data filtering.
