Devil's advocate: I've seen Redis used lots but by people who mostly didn't seem to know what they're doing: NoSQL bandwagon or other magical thinking: "It's fast". Yeah, but only because it does nothing to avoid losing your data or be HA (the disk persistency and clustering options don't have pleasant semantics ATM, as far as I can tell).
You can use it as a simple cache, and that's fine. But then why not just stick with memcached -- less is more?
There are probably some scenarios where single point of failure and data loss is fine and the additional data structures redis provides over memcached are handy (e.g. analytics), but I've never seen it used for that.
