I'm active on Blogger only, no Facebook or other such platforms.
However, several years ago, I opened a Facebook account for the sole purpose of following online city council debates on various topics. At that time what was especially of interest to me was the 'hot' topic of 'urban renewal', as my building was part of an area designated by the municipality for a big project of demolition and rebuilding. I soon became tired with these debate meetings.
Urban Renewal is a long, complex journey involving a lot of factors: apartment owners, entrepreneurs, contractors, neighbors, various local authorities, lawyers. Funding and Bureaucracy dominate the entire process.
The renewal plan for my neighborhood area didn't work out, but I kept the Facebook account as it enabled me to locate people in my past with whom I lost contact over the years.
I had no intention of reconnecting with those people, just curious to know about their whereabouts, and whether they were alive and well. Sometimes, my search didn't get any results. If I happened to know the name of their son / daughter, I would enter their public page trying to find out something about the parent/s.
Well, I was surprised to note that in most cases the off-springs did not mention their parents at all , at least not on the page to which I had access.They did refer ,though, to ... critters.
A few months ago, an 87 year old relative of mine , died in Bucharest (RIP). During her last years she was very ill, with Alzheimer and other health problems. Sadly, her only son (a fairly intelligent person, an engineer by profession), didn't even bother to mention her death on his FB page - no mention, no obituary, no tribute, no memories, no photos. Nothing. (I was informed of her passing by her sister -in-law).
I don't know much about Facebook and how it works, but I do know , that this kind of attitude is not acceptable to me.
