Most of the entries on the RepRap blog have been geared towards the technical. For those who’ve either not made time for or have no interest in following the actual development of the device itself, there’s another reason to head over: a thread discussing what the project means and what this kind of technology holds in store for all of us. The discussion (Link) has only just started, but hopefully there will be plenty of commentary… some of it yours I hope.
And btw, you might also want to check out Bruce Sterling’s talk at Lift06 (Link). I’ve not yet made time (partly because I’m familiar with the topic) but I do intend to watch the presentation. For a quick review of what’s discussed, you can read about it on Networked Performance (Link).
