It is entirely your prerogative not to have any social media. I also think it depends on your personal circumstances.
But I also don't think it's not that unreasonable for the school to state they have an active forum that's widely used/very easily accessible, and they update all their info on it? You could set up an account as private, no profile pic, and not add anyone beyond the school? Or yes they could send you an email/letter but the information may change within change very quickly during an emergency and you could be sitting thinking what's happening?
I agree with Wandavision though, and think that people who who profess to not having any social media at all sometimes comes across as a tad morally superior, and don’t understand how to use it to their advantage. You can set up an account in any name you want, not have any “friends” and set your privacy settings so that no-one can see them.
I am a member of a few local community Facebook groups. As a result, I know why our bins weren’t emptied last week, why our postal service is rubbish, that there has been a crash on a road near me and it is closed, why the local Hermes driver can’t deliver today, that our GP is now rolling out the covid vaccine, that local events have been cancelled etc etc – all sorts of very useful information. Like it or not social media platforms like Facebook and Twitter are by far the best way to impart information to the masses quickly and effectively.
Oh, and DD is at university, and our main way of keeping in contact is via FB Messenger.
You don’t have to have vacuous “friends, you don’t have to post vacuous stuff, or even post at all, but it is a useful communication tool if used correctly. I use Facebook. It doesn’t use me.
I have, or should I say had, two hobbies prior to lockdown that I've slowly been edged out of.
Mainly because all their contacting and arranging, especially since the pandemic has been mainly done via Zoom, FB or Whatssap.
Why would you cut your nose off to spite your face @likeamillpond? Are you trying to prove a point? What are your objections to Zoom? It isn’t social media. It is another form of VOIP, very similar to Skype.
