I think that programmers would generally be willing to overcome the inconvenience of the unusual notation, if the advantage of using defmacro was obvious from good examples to which they could, at least, relate. This question was also asked on stackoverflow: https://stackoverflow.com/questions/267862/what-makes-lisp-m.... My opinion is that the examples in the answers are neither obvious nor compelling. Hence, I am still waiting for better examples.
