Worth what? Your time? Your money? Your pride?
Your arguments in this thread lack specificity and, taken together, suggest to me that you are simply pissed off more than anything else. That is, you are angry...about something specific that has happened (even if it is was the "last straw"), but you are not going to go into that, at least not at first, but clearly you want to litigate your issues online.
I did take the time to go through your posting history to some extent and it seems that you did not act like you felt this way initially (you no longer recommend those videos to your students - so you did recommend those videos at some earlier time), but have now reached a conclusion and it is a global conclusion full of ad hominum attacks.
In fact, while I did not see much in the way of you asking for help, you have dispensed help - that you now condemn ("The "advice" dispensed by the members of this blog is useless."), yet, you have not just said your peace and left. Instead, you very much want to engage on the issues as evidenced by your additional posting in the thread.
It is, in some ways, unfortunate as your posting demonstrates that you teach. It also demonstrates, to me, a level of bureaucratic experience that may be taking its toll (you are still pissed enough to mention that your employer "forced you to do that") so many years ago. Taking its toll because your behavior suggests that you no longer appreciate the concept of near-peer mentorship (it is not just age-based) at any level through any media.
Even in your short posting history you are seeking acknowledgement for both your stature and your "solutions" - see the beginners thread in which you were, oh so critical, about what 'level' of answer should be given to a high school student vs a university student and so on - but nothing in the way of "agree to disagree" after making a point (and you most definitely did make a point, but it is not what I will remember about you and that memory will fade in a few days, if not a few hours). You don't seem capable of "agree to disagree" after making a point. You seem too pig-headed to see that such an issue is up for debate, that such an issue is not new and that educators in all fields deal with that kind of issue. In this regard, you have demonstrated a starkly disappointing insufficiency for self-evaluation.
I don't need to defend anyone here, but hear this well, this Dave guy has pissed me off a couple of times (never about EE matters) and I spoke my peace...and I did not back down...and then I continued...hopefully to make some helpful contributions to others seeking help and also to seek help myself.
Plenty of what is written will piss me off, especially when it is my area and is so terribly misinformed. That is how you feel now. When it is too much, I simply block those people so I don't see their rabble and don't ever respond to their rabble.
One piece of "food for thought" (and I suspect this will piss you off further) that I will give you is to ask yourself whether you should seek therapy on a public internet forum. Just as you yearn for everybody to go to the standard educational sources exclusively for EE information, and medical doctors for brain surgery, why not apply that to your anger?
So, I ask rhetorically (in this case. that means that I don't care much about your response and we both know that you desperately want to respond) - what is it you are after? I believe that what you seek is validation and you are likely not going to get what you seek here and now. Don't you get that?
And yes being your own boss is not all it's cracked up to be either......
Fortunately the problem is not as serious as you describe. It was just a simple case of intoxication. The next day, while having an enormous hangover, I saw what I did and changed my post to what I really think.
