Raindrop is a very innovative concept from Mozilla Labs. Like countless others these days, Mozilla tries to reinvent email (or rather online communication). So what is Raindrop? A simplified answer is that Raindrop is a communication aggregator with a focus on prioritizing and classifying messages. One of the core objectives of Raindrop is simply to distinguish generic newsletters or broadcasts from personal messages (regardless if that’s a DM on Twitter or a personal email). That sounds like a great idea, but how does it work?
There are three parts to Raindrop, a back-end that fetches the messages, a database (CouchDB) which stores the messages, and a web-based front-end that displays the messages. While Raindrop is still in a very early stage, this project has great potential. Raindrop has been designed to be extremely flexible and modular so as to enable simple expansion.
