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.
Same but mostly because I’ve had conversations with people who will Google something to tell me I’m wrong when the whole point was the conversation, not being right.
