I've done a startup that didn't go anywhere in .NET (Approver.com) and a startup that's getting traction in PHP with an MVC framework (CodeLesson).
I used to be a master of the universe with .NET (spoke at conferences and wrote a few books on web development with .NET). The fact that my prior startup used .NET didn't have any bearing on the fact that it flopped.
However, I went with PHP this time around because I knew I would have an easier time hiring people who know PHP, and this is proving to be the case.
In my .NET-based startup I did use MySQL instead of SQL Server as the data store, which helped us a lot this time around. Remember that the list price of SQL Server standard edition is $6,000 per CPU. This can be a pretty steep hit to a bootstrapping startup, discounts and programs like BizSpark notwithstanding.
