Many threads on GN don't "serve much purpose" anyway.
But this discussion has wider implications which posters are discussing as and when they arise. For example I had no idea Anniebach had received unpleasant comments on Facebook, I'm guessing in the recent past. That led me to think how in the early 1980s, in my case, when there was no social media there was obviously no public discussion, no comments in the public domain about anyone or anything.
On the other hand, the arrival of social media and the resulting media coverage has very much raised awareness too and it results in people talking too, as in the case of Nicola Bulley.
I would say the personal sharing of one or two posters on here only amounted to one or two out of 22 pages, if that. We certainly were not on this thread to dwell solely on our own experiences.
