However, the anonymous karma system is great, it lets people see who gives good advice without having to do a lot of looking at their user history.
So that would suggest that I don't give good advice which I would strongly disagree with. After over 40 years in electronics I feel that I am on my way to mastering some aspects of the subject at least.
