Fear of IP taint has traditionally kept most MSFT teams away from direct external contact, except through legal-approved intermediaries. Maybe Joel has forgotten that after fifteen years away? I'd stake money he didn't "talk to anyone outside the company" when working on VBA :-)
Unless there is some other computer-related meaning for the abbreviation DSL (besides Domain-Specific Language, of course) that I'm not aware of. :-D
In fact, when I read in general I read the whole sentence and parse it all together and not on a word by word basis. I thought most people read this way so that they are more resilient to typos and other small errors.
So if they simply do not recognize the term DSL->Domain Specific Language acronym, readers simply mentally flag it as a possible typo/other error instead of confusing the telecom notion with the um.. trendy ruby-world? term.
Not to be confused with "v dash", which refers to a contract employee from a vendor. In the Microsoft email system, contractors have an email that begins with "v-" and temps/interns have an email that begins with "t-", and just as employees are sometimes referred to by their abbreviated email aliases, contractors and interns as a group are referred to as "v dash" or "t dash".
Now you know... although I doubt you'll ever need to know :)
