I don't know about the rest of the (initial) team, but Joel was lead on Excel as I recall. If you have a group if devs that know the nt kernel, SQL server and iis very well - why would you not use the ms stack?
Don't get me wrong, I prefer Linux and Free software myself - but that doesn't mean the thousands of Man years sybase and ms have spent on their stack is wasted effort.
