Whilst I completely agree with you Alan lets try not to bite the hand that's attempting to feed us!

I went to the two JCS studio links and that was my immediate impression, that the information whilst no doubt invaluable, is of limited use if one doesn't understand what's being said.

A perfect example being the 'how to run two trains on the same loop' I'm sorry but I couldn't make heads nor tails of the description or the diagram. So what we need is someone to clarify and simplify the info, I think. Experts are usually the worst because they take so much for granted - 'well of course everyone will know what forward bias is' - that they are unable to see it from the students point of view.

Also having the gurus argue with each other over the details of this, that or the other example isn't at all helpful because it tends to drive away the poor novice who is probably hanging on by a thread to what he was just told and is now being disputed.

EE's need to come to grips with the fact that what turns a lot of people off electronics is the darn math, we're not all happy with formulas. However inaccurate it may be, its more use to say things like 'use a 470k resistor to protect the LED from getting too much current' (Thats NOT a real example) even though there is much more to it than that.

Well its early days yet, lets hope that together we can work out some means of bridging the gap between the gurus and the novices.
