Though I also echo what some other folks have written here: I'm occasionally jaded about yet another rediscovery and reimplementation of something already well understood. Here's another thing that experience brings though: a sharper focus on efficiency, the ratio of output to input. That is the thing I look for in each shiny new object that drifts across.
