It’s what employers want. Lots of folks don’t keep up and they manage just fine. Right up until they get laid off and need to find a new job.

I used MSDN and the MSDN blogs to keep up to date with Visual BASIC 6.0 updates. Things would change in the language, and I wouldn't know that unless I read MSDN docs. I got in trouble for using the Internet, as the Management couldn't see the difference between MSN and MSDN. It was like reading a book, only books go out of date in three months from publishing.
