Whatever fits the situation. No, really. If the {...} block form fits in 
an instance, you use that. If the do...end block form fits, you use that 
instead.

Caveat: The latter is most common if you deal with a multi-line block:

a_block do |x|
   puts x
   x += 1
end

Otherwise:
Indents are two spaces. Not tabstops of length 2, but the actual 
character ("  ").

And once you have written enough Ruby, you'll know what "feels" correct 
to you.
