    I got as far as paragraph 2:

    Unfortunately, Erlang is less than optimal at doing low-level stuff such as XML parsing, since dealing with anything that comes from outside of the Erlang VM into it is tedious

    In what world is XML parsing ‘low-level stuff’? Erlang is great at low-level stuff such as parsing binary wire formats, because it has rich pattern matching on binaries. It’s not that great at string processing.
