I feel like this is more a user/uncertainty issue right now. Reddit still has a lot more users than Lemmy, I feel like a lot of communities are spread across different instances (am I saying that right?), so no ones knows which will be 'the main one', and I think a lot of users are still looking around, watching and learning how Lemmy works, before fully committing and posting like they did on Reddit. I know I am.
How about !formula1@lemmy.ml or !formula1@lemmy.world?
Edit: linking the communities correctly still requires some practice from me
