I think the heat is getting to you @Gnasher 
, I am of course being a wind up. I appreciate your point but asking stroke survivors to manage their engagement is a bit like herding cats. I’ve been on this forum for six years, pretty much, joined a month after my stroke in 2020, and I’ve witnessed many a disgruntled member tackle the flow and form of the forum, some jumping ship and creating their own forums or alternative social groups, taking other members with them.
The forum does have guidelines for posting, the one that comes closest to your point is called hijacking a thread, where members go completely off-topic, and it has to be said that I, myself, have been guilty of doing this, especially when I get carried away with banter. We should be challenging others, courteously of course, as well as supporting them, that’s part of the rules of engagement.
I have to come back to my view, but still on-topic, that this forum means different things to different people, some people find it cathartic to mirror what they feel about someone else’s post with their own experience, some may read a post and respond to a different aspect of it, not necessarily directly related to the main statement or question, but we all read into things differently, I guess. Also, we are posting with our own set of brain
challenges, and damaged brains can be a bit off the wall at times, for instance, I have limited impulse control, so if I think to express something, it just comes out. This happens whether I am speaking face-to-face with people or writing on a space like this. Others will have their own reasoning behind what they are inputting, and in their mind it might very well make sense to the thread they are responding to, perhaps not to others, but that is a fairly natural consequence of personal interpretation. I think it is also worthwhile considering that there are many people reading the threads who don’t reply to anything, just read, and they will get their own takeaways from the conversation.
Anyway, just some thoughts on the matter. It is true that we are not medical experts or doctors, but I was misdiagnosed by a doctor while having strokes over three months. The doctor was convinced I had BPPV, and basically dismissed my concerns and left me with four strokes to manage for the rest of my life. Had I come across my own writing on this forum, as this forum is searchable, generally, on search engines, I might have had a stronger case for getting a second opinion with that GP, so I see the forum as; a resource, an outlet of expression, an interesting and entertaining read, a way to engage with others in the same boat (no matter the subject), a means not to feel alone, a place to vent, a space to share sad times and good times, a means of sharing experience and information, and a space to have disagreements too.
This is the only social networking platform I choose to have. Not on any of the others, so it is a bit of a virtual home away from home.
