I joined within weeks of inception, after seeing an article on it in the Observer.
I am another who feels that GN has lost its 'innocence' and openness. It happened around the time of the 2015 election. Up until then, there were political threads but they were broadly non-partisan. Yes, a lot of us had clear affiliations, but we could exchange views, and were open to new ideas, but suddenly political threads became partisan and vitriolic and gradually this has spilt out over many more threads.
I did drop out of GN for 6 months last year because I couldn't take anymore of the rancour and virtue signalling that then pervaded the COVID threads, but I returned. I could find nothing to replace it.
However, despite all that I still think there is no other comparable forum, generally clear of the bad language and hate that one sees on so many others.
Through GN I have made friend, who lives close to me and I have been shopping for throughout lockdown and by winning one of the prizes GN offers, I have been introduced to the world of Spa Days.
