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.
Especially since that discussion might be found later via Google as well. It’s more helpful to say that you looked it up via a specific search and give a couple of the results. That way it’s not a dead end and the person hopefully learns how to help themselves in the future by example.
