I've used it as you have for two things: - Storing user session data for high-use web applications. - High score tables.

And one more: - Storing diffs like those used for Google Docs (literally every change) for a real-time communication system.

The last one works by the client not getting a response and continuing to queue up its diff and send it once the server is back up. Manual conflict resolution is likely necessary after a drop in availability, but consistency is easy to figure out with monotonically increasing IDs.
