Asklemmy

You can do that in jerboa. The thing is that the name may not be exactly the same, and, depending on your instance, it may take more or less time, but searching for communities is perfectly possible.

Lemmy.ml and the other mainstream instances are overloaded, and thats why it appears as if it doesn't work

Is this a good idea?

Yes, this is how lemmy is meant to be used.

Is it causing increased load on the server end?

Maybe, if you're the only person on the instance that's subscribed to that community but it's not abnormal usage.

You can just search here for communities https://browse.feddit.de/

Though I also browse /all/ to find new communities I might not think to search for.

Mashing subscribe to anything looking interesting and seeing how it goes.

Removing ones that aren’t useful.

Reddid was / is a lot more lively, with enough posts in a day that I had to turn off notifications. Lemmy has not as many users around the world, and subocribing to a lot of communities does not equal reddit traffic at all.

I feel this is restful, and it offers the opportunity to learn new stuff. Also, by subscribing to different communities on different instances, you mix it up and make everything link together more tightly.

There might be a future when you have to currail your subscriptions, but just now, you are doing everything right.

Could someone tell me what jerboa is? That's the second time today I've seen that name.

I'm locating communities with https://browse.feddit.de and just subbing. I had prob 50 or so on Reddit. Prob will end up with the same here.
