It's weird that things as different as S3 and Redis all fall under the umbrella of "NoSQL". We should probably replace the SQL-NoSQL dichotomy with terms that more accurately reflect the real differences.
It's got an API, you can store data in it and retreive it later by key, since when was S3 not a database? It's a key/value store that lets you store very large values.

You don't consider Amazon/S3 or Redis NoSQL databases?

Since when is S3 a 'database'?

Not really a "distinctive" one (a la mongo, couch, etc.), but I see your point.
