Elevator Pitch

Hi there, I am a blog user of “Blogspot” with much knowledge about PHP, .NET and MySQL. I found blogspot is easy and normally used as a student. I build this blog for practice and improve my knowledge and abilities to understand more about how Client-Sever-Database system works, dose XML better than HTML or XHTML, dose JSP or ASP.NET works well than PHP, what are the differences between them. We have a group of people working on this as a class named E-system Infrastructure Development. We give comments to each other to improve our abilities and share our ideas, but that is not enough, to help me use your power, could I get more comments from you?
