I accepted one of the answers in 2010, but then over the years after gaining more experience in Redis myself (painfully might I add) I later realized that a more recent answer actually is a better solution.
So I went in recently and changed the accepted answer to the more recent and better one.
I felt weird about doing this given that rep points are involved, but between having someone lose rep points vs a larger group of people potentially going down a sub-optimal path, I chose the former. Anyone else feel weird about this?
