etcd use case

[emplexity]

an introduction about the use case of etcd would be welcome, the demo is already deep in technicalities for an outsider willing to figure out what is the value that this software could bring.

Discussed during sig-etcd triage meeting - @emplexity thanks for the feedback, the use case for etcd is highlighted very prominently on our main page: https://etcd.io

A distributed, reliable key-value store for the most critical data of a distributed system

etcd is a strongly consistent, distributed key-value store that provides a reliable way to store data that needs to be accessed by a distributed system or cluster of machines. It gracefully handles leader elections during network partitions and can tolerate machine failure, even in the leader node.

If you have ideas to make this clearer could you please let us know what you have in mind?
