Steve, you're probably talking to a bot, designed to collect some karma points, to be used for upvoting/downvoting some important article or comment in the future.
some uses for redis, as we use it:
* pubsub (publish/subscribe) - push information through to other servers on channels
* job queuing - redis supports lists, which can easily become job queues
* statistics - redis supports incrementing and decrementing keys very quickly and easily, allowing for real-time statistics gathering and reporting
hope that helps.

My account is only 5 hours old because I created it to ask my question. I am relatively here and I was just lurking before.
