I have to say this: I am the architect of Pharo (bah, the guy who has the responsibility of putting the pieces together and handle the releases). While I cannot do anything about it, I do not feel comfortable (and I know a lot if not all the members of the "core team" either) with this kind of "evangelisation". We love our little environment, and we certainly believe it has merits enough to be considered a player in the language ecosystem. We do our language with passion and conviction, but also with respect for other languages and programmers.
While the author has the right to do as he thinks is the best, please consider this is not how the team developing Pharo thinks and act.
