Don't feel too weird about it. I think expressing things like this, just putting it out into the void, especially on a place like cohost, can result in input which helps reduce those isolated feelings. We're all out here without manuals on how to interact well with others, and some have more or less social skill than others.
I've always struggled with social anxiety but the thing that's helped me gain ground on the gnawing self-conscious feelings online has been pushing myself to at least leave simple comments on other peoples posts. Positive reinforcement is the best way to learn that you don't have to be so self-conscious. When people would reply to my simple comments and it wasn't a negative experience, my poorly socialized brain began to understand that its fears were blown way out of proportion... so those fears began to shrink.
I don't think it comes naturally to anyone, but I think a lot of people get lucky and have personal situations when young that allow them to learn social lessons early, while some of us others have to learn them later which feels like a real uphill struggle.
But yeah, the best way to learn online is to reply to replies on your posts and reply to other people's posts. Even if you're just remarking about how you enjoyed an aspect of something the person is posting about like a piece of art, story, anecdote, meme, whatever. Small interactions will build confidence and the chasm will shrink over time ^u^
