Good to see, but as with all posts like this, it’s important to note that the really important number is “Active Users” That number has gone up significantly as well, just not as fast as number of accounts.
It took me months to actually start using Lemmy and Mastodon. I would consider myself a tech savvy person and it still took a while getting used too. I think there need to be better tutorials linked on the sign-up pages that help people understand the basic concepts. That would help drive true user acquisition.
Do you need to for some reason? You can subscribe, comment, and post to any community that's federated with your home instance.
If you're on Lemmy.ml and the comm you want to sub to us on Lemmy.world, you should be able to find and subscribe in the "communities" section. As long as it's filtered for all communities and not just your "local" instance.
From the docs: "Lemmy also shows counts of active users for your site, and its communities. These are counted within the last day, week, month, and half year, and are cached on starting up lemmy, and every hour.
An active user is someone who has posted or commented on our instance or community within the last given time frame. For site counts, only local users are counted. For community counts, federated users are included."
