On Lemmy, you might find it overwhelming by looking at the all communities feed and then blocking those you don’t like. Instead subscribe to the ones you want and then just view the subscribe feed.

Personally, I use all to find more content and block communities I don’t want. I then just jumpnjnto subscribed occasionally of there is too much junk.

It’s a shame that there aren’t finer controls, like to ramp up and down communities rather than just block or subscribe. Some communities, I wouldn’t mind seeing their popular posts but I don’t want to say the hordes of junk posts. Only option is to block.
