As poetic as "everyone IS selling something here" may appear to be, it is far from correct. Especially in early posts (mine included), there were some views and some thoughts, but there were also plain questions with not much else added to them. I am not sure if they were simple as people who posted them seem not to be satisfied with clarity of answers. Maybe those asking are out of tune with those answering. Putting attitude in explanation how everybody is selling anything definitely opens the door for not allowing further questioning by those who question, but has nothing to do with reality. I repeat, there were at least a few posts with questions without any opinion and those people were clearly not selling anything, not even attitude, if that can even be sold. Elizabeth's post reminded me of the way many of my friends in their early twenties were trying to charm girls with deep intellectual thoughts that, in the end, had no meaning. Parallel worlds on two different energetic levels and such.
It just happens that I showed this thread to a friend whose comment was "what is this, some paid advertising forum, the guy is trying to push his thing without answering any question when asked directly". Just like to your friends, who may be a bit biased because they are your friends, other friends with no bias (I just showed the thread and made no comment about anything) may have a different view.
It comes across as your friends mocking retired people, but they are not completely correct. For my part, I am not retired. In some way, I do have to agree with your friends as, many posts ago, I did mention that having Planck, Einstein, and Kim Jong Un in a thread about nothing existentially important (at least to those who had no interest in selling anything) shows we all have too much free time and should go back to doing something. It would be interesting to find out how many of your customers are retirees. I do not have even a wild guess.
Is reading Tuneland supposed to make people converts to whatever is there? OP was not even about Tuneland. Nor was it about Planck, Einstein, or Kim Jong Un, for that matter. It seems that things take turns to unexpected directions originally unrelated to the post.
In this particular thread, I am not taking any side and give a benefit of the doubt that some things may work (tuning) while having some doubts about the extent and usability/practicability of such approaches. I may never know. However, I do notice that thread started seeming more of a sales pitch and, for a lack of better word, ridiculing those posters who are not full believers.
On a completely different note, is there any use in demoing tuning system in a room in Las Vegas and believing that different equipment thousands of miles away will get the same benefit?
