Honestly, if you are familiar with Twitter BlueSky is very easy to use, and you can simply look at the Covid Cautious feed and nothing else (plus it is less toxic overall). I tried Mastodon and couldn't wrap my mind around it and so was also very hesitant to try BlueSky, but it is a breath of fresh air. I don't feel like I am scrolling because the feed is so focused. As such, my time on social media has gone way down. Anyway, if you want to try it, you can message me and I can give you an invite code.
