THAT'S TRUE even just that much would probably help.

I think as far as for posting goes for just witnessing stuff like, at least in my situation, Pink isn't normally super keen on sharing with people as a general concept. Depending entirely on why he broadcasted something, or if he was intending to share or not, direct follow up threads would just be him redirecting or not engaging with the thing the thread should ostensibly be for engaging with. Active pursuit makes him more likely to try to dodge, basically. Also I don't generally think of his memories as stuff that would garner a lot of active reactions so much as like 'ah, that's why he's like that' (though maybe I'm wrong, I haven't been trying to engage with the memory regain mechanic more until recently!) So for me I'm imagining like, I want him to have broadcasted a memory and want people to have a chance to witness it and know a little more about him, but mostly it's for the sake of maybe informing people's opinions about him, and that can just come up naturally in threads later without having to thread about the memory itself.
