Because nobody has written the code to make it “not function like that”.
Posts on Lemmy be like:
Are you submitting posts without reading them first? If not, what's the issue?
When you submit a post, often it's to have a discussion you'd like to follow, advice or info to gain from others, etc. Lemmy marks these as read since you've obviously seen them to create them, even for your own posts, so they don't show up under "posts" on your own profile. Having ones own profile be blank of posts because you'd like to have fresh content everywhere else seems like a miss.
I think the issue here is
they don’t show up under “posts” on your own profile
It makes sense to hide read posts on the main feed, but not when you're looking at a particular user?
Yes, it makes sense to hide posts in any community or all, but not one's own posts or own profile.
Don't you get reply notifications? I get reply notifications.
I also don't check "hide read", though, so we're clearly using the platform differently.
Reply notifications serve the immediate purpose to take you back to the thread if you want, but having a personal post history that is blank because I prefer fresh content in communities is strange to me especially in a nacent project with limited content on many communities.
