Thanks to Chris, the system I worked on has since been replaced several times over and I'm pleased to announce our newest system is live today. One major improvement is that it's faster than ever before -- it's practically live. Head to your recommended page and vote on something and the recommender should whisk it away and give you a new recommendation within seconds.
The technology we're trying out is new and unproven -- and we appreciate you bearing with us and helping us out as we've tried to get it tuned over the past couple of days. And, of course, we continue to want to hear your thoughts about how it's doing. But the most important contribution you can make is simply to vote on stories on your recommended page and teach reddit what you like.
We continue to work on new and smarter recommendation algorithms. Lately I've been working on smarter ways to find stories on blogs that might interest you. I've posted some of my early results but there's still plenty more work to be done. Thanks for sticking with us.
