I don't WANT to make posts about fashion, cooking, politics, or non-techie things, but if you do, then by all means, please do that?
I didn't ask you to do those things, specifically. What kinds of hobbies do you have? Talk about those. If your topics are all tech-focused, that's fine, keep talking about those, but I'm really hoping I see people here talk more about pomeranians and nail polish, even though I'm not into either, because those topics will engage people who are into those things.
And now we both are breaking your rule: discussing things about the fediverse.
I think you misread my post. I did not say people should not talk about the fediverse, I just think we should post about other things, too. Especially if we want to see the fediverse succeed, we need more than just the meta-conversation.
