What is frustrating about this site is how many knowable people there are reading and belonging to this forum and yet no one has given you a cause and effect of oven spring.
There is an element of truth in what you say. However, at any given time, there are only a small number of members who actively assist other members. Most members who join this forum do so out of self interest and come here looking for something. And they wish to get what they are looking for for nothing. In the vast majority of cases, they leave once they have gotten (or not gotten) what they were looking or hoping to get. I personally have over 19,000 posts, and closing in on 20,000 posts. Yet, I would estmate that well over ninety percent of my posts were addressed to members who are no longer here. Since I am also a Moderator who has to look at over 6000 new posts a month and over 70,000 new posts a year, that leave me with little time to devote to individual member issues or concerns. That means that I have to be very selective on what I post. I think other members who actively help others often do the same thing. They don't want to get too involved with other members when they know that the other members are unlikely to be around for long. They will reserve their best work for other active members or other members who show great promise and may stick around for a while and give something back to the forum.
A lot of members address their questions to Tom Lehmann even when there are other members who can provide the help requested. Since Tom has a full time job with the AIB and writes for various pizza related publications and participates on other forums and in industry/trade events and is also a teacher and consultant who is on the road quite a bit, there is no way for him to answer every question or request for help directed to him. And he is among the most generous persons with his time that I know of in the pizza industry. Also, I suspect that there are members who choose not to respond to questions directed to Tom out of courtesy, given that the poster intentionally sought Tom out for help. I often play the role of facilitator to gather more facts to help Tom provide a fuller or better response but, on occasion, I will provide answers to basic questions that do not need Tom's personal attention.
I appreciate your efforts to help others, much as others have helped you, but as a realist who has been around this place for about 9 years, and most of that time as a Moderator who sees everything that goes on on the forum, I am not optimistic that every member who comes to this forum will always get the best of what the forum can offer to them.
