I've posted my opinions on Ruby-Core, but I'll summarize them here:

1. The Ruby community should proceed with all deliberate speed towards
ISO standardization of the language.

2. There are two "de facto" standards for the Ruby language at present.
    a. Ruby 1.8.6 as documented in the Pickaxe, Second Edition
    b. Ruby 1.9.1 as documented in "The Well-Grounded Rubyist",
"Programming Ruby 1.9" and "The Ruby Programming Language".

   All other versions are irrelevant and a waste of precious developer
energy as far as I'm concerned.

3. I don't think it matters what the numbers are, but since the two
"de facto" standard versions have designated numbers already, why not
keep them as they are?

4. Since I don't personally have a large installed base of Ruby code,
I am going to use 1.9.1 whenever possible to
    a. Take advantage of the YARV engine.
    b. Put some mileage on the implementation, shake out the
documentation, performance tune, etc.
