Wow! Thomas Lewis who works on the ASP.NET evangelism team (and who recently gave me some good feedback on starter kits) sends this gem from Netcraft.
In this month's Web Server Survey the number of IP addresses with sites using ASP.NET has overtaken those using JSP and Java Servlets. The number of IP addresses found with ASP.NET has shown very strong growth in the past year with a 224% increase from 17.2K to 55.8K. JSP & Java Servlets despite being overtaken is the next fastest growing in percentage terms with a 56% increase.
If you're keeping score at home, Java started in 1996. ASP.NET started in 2002. Within two years we're ahead, that's huge momentum!
