I am not that good, but I have used echo location since I discovered it
probably before I was three.
I have no idea why it isn't taught.
The advantage of a click when compared to a cane tap, is that the sound
emition and reception points are close together.
This American Life can be subscribed to with a program like juice, i-tunes,
or the stream.

This is a pretty good program called, "This American Life," but wait until
you have a lot of time to listen to it because it's long like close to 2
hours.  It's about echo locating which is the skill of blind people getting
around by clicking with their tongues to let them know where they are.  I am
skeptical of it, but in his case, it has produced some results.  I didn't
download it, I just listened to it.

Blind ham Bob Ringwald has a very brief segment in it, and the NFB is
briefly mentioned.
