Top business sites using SQL Server database

Hi,

I know it might sound silly but I just wanted to ask what are the top websites using SQL Server other than Microsoft and MSDN?

I am planning to move all my personal and business project to SQL Server but still using PHP... I checked the comparison between MySQL and SQL Server and did not find any major difference, in fact for me Filestream is very important which MySQL does not provide.

That's why I thought to search for top sites using SQL Server database..

Thanks,

Jassim
