> Memcached doesn't pander or resort to marketing to achieve a userbase (compare to redis/labs)

I think this is pretty unfair to Redis. Redis has a lot more features (tell me which ones you think are pandering, and to whom?), is free for the vast majority of what people want to use it for, and the attempt to make some money through Redis Labs is pretty recent in the scheme of things. If that helps with the continued development of Redis I have no problem with it.

While I don't want to take anything away from memcached, I'm puzzled by the swipe at Redis. Whatever marketing you're referring to, Redis supports some pretty useful data structures that make some pretty common query patterns trivial (eg top-N queries) and does it with a small, elegant core of some of the most readable code ever produced.

Memcache OTOH is a fairly simple KV cache. It seems to be pretty decent. Neither of these supplants the other however. Hence my puzzlement. It just seems out of place, unnecessary and doesn't really add anything.

Thanks!
