Umm redis is really cool. Nice job on this antirez. I've just finished implementing the entire spec here:
http://github.com/ezmobius/redis-rb/blob/0951204e6a84ca335ac...
And I am really enjoying being able to store lists as values and pushing/popping/indexing. Looking forward to where you are going with this.
Although the current release doesn't seem to support all the documented features yet. incrby and decrby don't work yet.
Can you get in touch? I'd love to pick your brain a little about redis.
