I believe Loopt was on C# stack and its founder is currently leading YC, so I'm sure Paul didn't take stack too seriously when evaluating companies. There are a lot of good reasons to use Microsoft stack, and I suspect more than a handful YC companies use it. Paul said it is advisable to not use enterprise technologies if you're willing to attract high quality engineers only. He never said it can't be done and it is never implied that high quality small number of workforce is important to every business. If you're in consulting, for example, you'd want a larger workforce you can get for cheap. But I think you already mentioned that point, just throwing it out there.
