You can 100% just keep using your lemmy.world account!

The reason why you probably didn’t see anything after subscribing to !wetshaving@wetshav.ing is because there’s not much activity there (yet). When you subscribe to something using Lemmy, the Lemmy software doesn’t really go back in time and show you older stuff.

I just made a post over there if you want to make sure it’s showing up in your feed.
