Jack,
Consider this is his business and he will let us know what he can/wants. The problem with answering via PM is that sometimes the information asked of him which he reveals is either unimportant or secret insider info. If he answers things via PM its often because he trusts the person he corresponds with and would like to keep it between them, otherwise he would post it up himself. So if a question you asked goes unanswered, consider either hes read it and considers it not an inportant detail to get bogged down in, or it could not be convenient for him to reveal. It is a business after all, and though Shanti is more transparent about his lines than the majority, there is no real reaso for him to give the public the exact formulas to his breeding programs. They are, after all, the results of years of his hard work. He expects us to be happy enough with the seeds, and when the seeds and the flower arent enough, and we delve too deeply into history and lineage, he (Scott) may believe that we should rather focus on the selection and working of his lines to find our answers, rather than look back into the past for what may or may not have been.
Some questions will simply go forever unanswered, and the ones he does answer, is a privilege, as he´s under no obligation to do so. Plenty of seed companies have hacked his work, so Im sure you could understand his reticence at answering any question coming his way he deems unimportant or too delicate. So normally, if he does answer one of these questions via PM, its out of respect and caring for the person who asked. And sometimes keeping this info to yourself is more than enough. Personally Ive been told my fair share of company secrets, even before this current moderator job, but have been satisfied with knowing these answers. Sharing a private conversation has been less important.
Hope this helps.
