Evolutionary - no fine is not enough. If you can choose between bad, fine, great - you pick great unless it's takes too much resources (time/currency/etc). In this case the constraint are "open source workload" which is quite massive nowadays - then consider a "fine" site hacked together in an hour a good solution on this problem is "not enough".

Now it seems the picked path for ruby-lang is open contribution, that is not just "fine" - it's great.
