This question is especially for people who have joined in the last week. Have you used other fediverse platforms or is this your first time really using one? What do you think of it so far? Are you aware that you can comment on Lemmy posts with a Mastodon account?
Joined Lemmy last week but moved to kbin, I've been on the Fediverse for a few years now. First joined on Mastodon, but now I actively use Calckey, Akkoma, and am a mod on a Peertube instance. As for what I thought of Lemmy, I liked it, but I was more curious about kbin as I'd heard about it for a while
Go to the search page and put in a link to a kbin magazine (what lemmy calls communities and reddit called subreddits) for example https://kbin.social/m/tech
It might not have any content on it until you or another user on your instance subscribes to it though
Once you subscribe from the https://lemmy.world/c/[email protected] page it will show up as a subscription for you on Lemmy until you unsubscribe so you don't need to search for it every time
