Secret language

Jargon arises because it is useful for compressing information exchanged within a given culture. If this really was an internal posting which was accidentally exposed, what is the problem with using the jargon of Microsoft's culture?

Judging from their performance in the marketplace, it sounds like their internal jargon describes a model of the competitive landscape that's pretty successful. Just like in programming, any model complicated enough is best expressed in terms of a DSL.

Microsoft is certainly not the only guilty party in this respect. Overuse of jargon and, more egregiously, failure to appropriately define all but the most universally well-known abbreviations at the point where the abbreviated form is first used in the text is a pervasive problem in the field. For example, the first few responses to this article use a total of four domain-specific abbreviations (IP, MSFT, VBA, and DSL), none of which were defined by the authors. Worse, within the field, the meaning of one of the abbreviations (DSL) is context-sensitive and the author's intended meaning is the lesser known one. The appropriate convention, used in virtually every other technical domain, is to explicitly state what the abbreviation or acronym stands for when it is first used in the text and then use it as much as you like in the rest of the text. Only a very small subset of abbreviations that are certain to be recognized by everyone in the field, regardless of their subspecialty, may be used without defining the term.

OK, but to be fair to MS, this appears to have been written by a nonnative English speaker. Indian, I think. So there's another factor at work.
