I don't think you are going to see any glitzy sales pitches for VS.NET on here (come to think of it, do we do glitzy sales pitches aimed at devs?).
That's what I think the gist of that part of the manifesto deals with.
As a marketing goon at Microsoft I can state that while the mere word "marketing" has something of a bad connotation for the more technically adept floating around the halls the actual implementation of it (the writing, the assitance in planning, the creation
and implementation of ideas, the day-to-day work) does generally meet with appreciation.
As for the wording in the manifesto: I think it may have been a better choice to say "No sales pitches" than marketing.
But that's just an opinion from a writer/marketing goon.
