Akthually, Betamax and betacam were completely unrelated standards. Betamax was the failed vhs competitor, with good quality but an unusably short recording length, and betacam was the unrelated standard that enjoyed a long and successful run in the professional world.
Technology connections has a few videos on the subject, but this one is probably the most relevant: https://youtu.be/hGVVAQVdEOs
My strategy on Reddit, which worked very well there but I’ve been too lazy so far to recreate here, was to create separate accounts. I had one account that just followed f1 stuff, and another one that followed all my general content and had all the f1 subs explicitly blocked. That way I have to actively choose to switch over to my f1 account if I want to see f1 content, which I just wouldn’t do until I’d seen the race.
A lot of the lemmy apps, like voyager and Memmy, already have good support for account switching, so I highly recommend this strategy if watching the race later is a regular occurrence for you. I’m sure eventually I’ll bother to do this myself.
Alternatively, whenever the analogous multireddit feature gets implemented in lemmy, that could allow you to do effectively the same thing with one account. But not yet, unfortunately.
