Ruby interpreter / version for greenfield project

Hi all,

I wanted to ask the list about the current thinking on which of the many interpreter and version options is currently favored for a brand new project. I’ve been using the most recent REE release for many recent projects simply because a lot of gems and plugins hadn’t yet been made 1.9 compliant, but I think this is probably not as big a problem as it used to be. So what would you use?

Wherever possible, please supply the arguments and factors that led to your decision, and thanks for your inputs.

I've moved the app I work on to 1.9.2 recently - we didn't have any
major problems with gems/plugins not working, although there are a few
bumps in the road - we found something that made
validates_inclusion_of slow and rcov seems a bit borked
