The "just google it" mantra has probably held back quite a lot of interesting conversations and debate
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.
Not to mention that Google is also terrible for retrieving some (most?) kinds of information. It can work with basic facts but then you're still relying on Google (or any other search engine) not to omit other salient facts or sources.
I was like you and mainly lurked for this reason, too. The fediverse can be a lot friendlier. The atmosphere had changed a little since the latest Reddit exodus. Hopefully, most of the toxicity of that platform is left behind.
It might be helpful to reiterate that knowledge isn't fixed and the while Google provides one answer, we could get a better answer after a discussion. So keep asking questions!
