Why does it have to be only one or the other choice. It is a public forum, so there will always be good info and bad info whether it be from a pro or a hobbyist.
As in the real world: There is a place for both groups. I want the pro's doing my nuclear reactors, hazardous chemical pipelines, petroleum lines, vehicle hitches, cargo trailers, etc. Hack's like me are fine for non-critical repairs to stuff where no one is going o get injured if it is done incorrectly or fails. I am not a pro basketball player either, but it certainly does not mean that I do not enjoy playing the game anyhow.
The key is reading the posts and pretty soon people with some sense will likely choose who to trust and who to basically ignore. I read many posts that I never respond to both from the pros as well as the hobbyists simply because I enjoy reading them.. I also skip posts by some posters whom I do not care to waste my time on. Can not go by post counts either. Not so much on this forum, but on another forum that I frequent I soon learned to skip over the most prolific poster on that board. Frankly, there was never anything worthwhile in any of his posts. Useless posts about absolutely nothing - a pure waste of my time.
