>> Asking an expert and getting explained is invaluable, but what I found particularly disheartening is the treatment of ‘noobs’ in amateur electronics forums. Being insulted when asking questions is not pleasant. I thought ego issues were unique to software development communities, but they were not. If you need to ask questions on the forums and you’re learning, you better have tough skin.
