To be fair, if you want content on Mastodon, you have to actively go out, find people, and follow them. After you get past that Step 1 of signing up, your home page is empty. There’s no algorithm that automatically deposits content on the main page. You have to do a little bit of work to get anything. As you say, doing this work is not that god damn hard, but sadly for about 80% of people (maybe more), this is an impassible barrier.
On the bright side, once you do get past this barrier, none of the Mastodon content that you are getting is from that bottom eighty percent.
The exact same thing has happened to me. I still have a beer every now and then (like once every two months or so). I pretty much can honestly say that if I drank any less, I wouldn’t drink at all.
I’ve never been that much of a drinker, but once I reached my forties, having a beer or two would invariably mean that I would need to take a nap a few hours later, and I just don’t need that interfering with my day. And I am cognizant of the recent studies have shown that there is no health benefits, only detriments, to any amount of alcohol at all. And add that I would pretty much always prefer the taste of a diet soda to a beer on almost any occasion, I’ve pretty much almost completely phased out alcohol in my life.
It helps a lot when most of your friends don’t drink much, either. That said, does any one else really care whether you drink or not?
