No invention has received more praise and abuse than Internet. No one can deny the fact that  we must learn more to adopt it , as .Net  Web2.0 and Asp.Net come to us.
 It is a serious problem ,recorgnizing  day and day ,that i must update my knowledge as soon as possible as i loss a so many changes that feel that knowledge is out of season.
It's time to study hard。
Remember that.
