You might be right about the general meaning of the term "block." However, in Ruby blocks happen to be implemented as closures. This was one of the main points

  That's a totally legitimate point. I'm just pointing out that the quoted bit would lead the reader to believe that a block is defined as a closure. The problem is almost everyone I talk to in the startup scene thinks that an anonymous function/block == a closure.

This is a big pet peeve of mine - I keep seeing people use 'closure' as a synonym for 'lambda'. It's a simple error, but it bugs the hell out of me. Then again, it's a dead giveaway that the person has never programmed in a functional paradigm, which may be a good thing to know, depending on the context.
