We all have our disagreements. My own arguments with Erik did get very acrimonious. But why should any of that blame, if any, lie with Craig? I am still posting and are so many others. What fixing do you want?
May be some of the "seniors" are posting less:
1) They have become more focussed in their field, posting only in topics of their interest.
2) Busy with something else.
3) Tired of answering same old student questions?
And many more reasons.
Nearly all three apply in my case! Even then I am urging students every year to visit this forum.
So what should Craig do? Reward the "seniors" with box of candy/ chocolates every year?
Come to the Microchip forum, the situation is the same, only a few regularly post.
And Puleeaze, Craig is doing it for free. How much more time should he devote? Start your own forum if you are so unhappy. I am sure Craig will have no reservations to posting that link on this forum.
