S4
<i>S4 is a general-purpose, distributed, scalable, partially fault-tolerant, pluggable platform that allows programmers to easily develop applications for processing continuous unbounded streams of data.</i><p>I'm sure this is cool and useful technology. At this moment, from the marketing-speak, I have no idea what it does except that it has something to do with volumes of streaming data. Whose data? Is it a service? (Maybe not, since you can download it?) What could it do for me (in simple terms)? What's a basic use case? Why do people assume that we can mind-read?
