I received some information about this Port80 survey through the MS email chain. It very clearly shows that ASP/.NET and IIS are rapidly becoming the development platform of choic for many companies. Here are the surveys and the related press release that I'm talking about. I have to say that I'm rather surpised by the numbers, but also very excited. I guess more people need to get introduced to blowery's HTTP compression module to get the numbers up for HTTP compression. I for one, have started to use it on most of my sites.
