A ruby guy here says most people should be on 1.9.3 -- my understanding of ruby is that 1.8 and 1.9 were sufficiently concurrent that you have a similar situation to python. Apparently 1.9.2 is buggy, so supporting 1.9.1 (and 1.8.6 or maybe by then 1.8.7) seems sensible.

On the python, +1 on 2.6. Its going to make migration to 3 easier. I think the metric these days is to do what Django does.

Yes, I agree completely. 1.6 seems to be a sensible floor for support.
