Have been having the problem of LLMs sounding too boring and corporate too.

And this is a really good reason to just stop using LinkedIn and X, all in one easy package. There's just no point being there if you're not a business. I vaguely recall that LI used to be a social network (loosely speaking) but that's pretty much meaningless now. It's just another advertising platform, being taken over by AI's.

Now what it needs in an AI that reads those posts and responds (or doesn't), but it's pretty much unnecessary for actual humans to use it.
