I use LinkedIn. I’ve posted some blog posts on both Hacker News and LinkedIn and determined that LinkedIn is a bit more evergreen. A post on the HN front page gets thousands or tens of thousands of views in a day but a LinkedIn post has thousands in the long tail.
I think a lot of accounts are playing the algorithm and have AI generate a post every week. I just ignore those. Most of my posts are one sentence followed by a link to a blog.
Truthfully, I think it’s easy to rise above the slop since so much of it talks about the same stuff in the same format.
