The trick is to sort the wheat from the chaff!

I've lost count of the number of technologies/technology companies that were going to be the next big thing, but after a flurry of excitement they vanished into the ether.

When you start off in the IT game both your time and your money (after taxes)are your own so keeping up isn't so much of an issue.

But as you progress through your career you find that there are 1001 things demanding your time and nappies cost a fortune so have to be careful not to waste precious time learning something with a short shelf life.
