Hi Neil,
Nice to meet ya! This is something that I've got a little experience in, so I'll try and draw from that.
I first joined Treeleaf in 2015, but after a short period of time I simply practiced with everyone in the background: Sitting one-way with the YouTube zazenkais, browsing the forum but always reading—not posting/replying, and yet, I too maintained that sense of closeness and community—even if not visible to others.
This lasted up until last year, when Ango came around, and thanks to the gentle nudging and support of our sangha-mates, I started posting, replying, sitting live with everyone, making the tea-houses, etc. I can say that I do wish I had done so much earlier—but—it also worked out just as it should have, I think.
Which leads me to answering your question: I don't think anyone would be annoyed (I wouldn't), if you asked/posted something that pertains to your practice or zen or life in general. You may be shown links to say, the Beginner talks, but overall, I believe it's good to ask questions if you feel called to. The answers you may find searching may have came from years ago—and those answers and individual's understanding and expression of the same question could be much different today. So it's always worth asking, IMO.
From the Lankavatara Sutra:
So, ask away!
Sorry for running (very) long,
Gassho,
