I’ve always been a “lurker” on all platforms and communities because when I do have a question or would like to contribute my first thought has become:
Actually, let me google it first
In which case I’ll usually have some answer. Usually it isn’t a complete answer but enough for me to not want to share my question anymore.
There’s also the benefit of discussion. You can find perspective on information which is arguably just as valuable as the information itself. Wisdom isn’t just knowing the facts but understanding them in practice and in proximity to other facts.
