Hello Roy,
I haven't read that long thread you referred to but the answer to all your valued observations must rest with the individual, so motivated to reach out for assistance. The Tek group is unique gathering of expertise, fine documentation, complementing many other web sources of information for the Tek brand. However, a key distinguishable feature is facilitation of first hand contact.
The overall benefit of the Tek Group is surely sharing of valued information, but no single member is obligated to act as a mentor. Learning from others however is a fundamental for individual development, including making mistakes and building resilience.
