Taking on a good suggestion from Jon Hurwitz, I would like to introduce the above question.
In a recent Metacase webinar about DSM, I asked Juha-Pekka Tolvanen who was MetaEdit+'s biggest competitor. His answer was: "developers". (By the way, you can still attend the Metacase webinar at http://www.metacase.com/webinar/WebinarFeb2009.html
So one of DSM's thinking leaders recognizes that convincing developers of DSM/MDSD's advantages is the greatest hurdle.
Therefore, MDSD evangelism is required! How do you think this can be achieved? Seminars, Webinars, a great Powerpoint presentation model, hands-on videos, case studies?
