I try to keep things simple when it comes to social media. I still have Facebook but don't really have much time for it. I'll check the notifications from time to time, but I think I miss a lot/most of my friends' posts. All of my Facebook friends are people that I'm aquainted with in real life. I don't accept friend requests from strangers.
And then this year, finally, after many years of resistance, I joined Twitter (mostly because I wanted to get horse racing news). I enjoy reading the feed during my commute, but I get notifications for accounts that I'm not following (mostly people who are dying from cancer or had someone close to them die from it), which is very annoying. I don't have cancer. I don't have a particular interest in it. I mean, I'm sorry that your kid died, but who are you? It's weird. I guess it's the algorithm. So it's a little upsetting that I finally relented (after all these years) and signed up for Twitter, and now the platform is changing so suddenly and so drastically.
That's about it for me. I can't think of anything else. In terms of food, I'm happy with EYB and finally have become comfortable enough with my phone's camera to start posting photos in addition to recipe notes.
And as far as entertainment goes, for years now I have been using a site that was called RateYourMusic.com but also added films about a decade in--so I use that to rate and keep track of movies that I have seen and/or want to see. I used to read the forums too but don't have time for that any more.
I don't know what Mastodon is. If it's food-centric, I'll have to look into it. And this is also the first time I've heard of Threads. (As you can tell, I try to keep social media accounts to a minimum.)
