You're a little off. If Beehaw defederates with lemmy.world, users of lemmy.world can still see everything that users in Beehaw post in that instance. However, Beehaw users can't see anything coming from lemmy.world. Instances have their data on their server and pull data from other instances periodically after someone subscribes to a community in another instance. In the Beehaw/lemmy.world case, lemmy.world's instance will keep pulling data from Beehaw like it always has been. However, Beehaw won't pull any data from lemmy.world. So, lemmy.world users can still comment and post "in" Beehaw communities and threads, respond to replies in threads from Beehaw users, or respond to other lemmy.world posts/replies, the only thing is that Beehaw does not copy any of that data from the lemmy.world server back over to its server. All of the posts made in Beehaw communities will remain local to the lemmy.world server. Does that make sense?

Your muscles are going to get stronger way faster than your joints. A lot of holds that are ~V3 and up (depending on how your gym grades things) will end up putting a lot more strain on your finger joints/ligaments than the big, juggy kind of holds you see at the V0-V2 range. If you're having trouble with really crimpy holds, that's probably a good thing if you've still only been climbing for a couple of weeks. You really don't want to sprain a pulley tendon, it sucks.
So, for now, be very careful about putting excess stress/strain on your joints, especially your finger joints and elbow joints. Those tends to be the easiest to mess up, in my experience. I would advise against trying to do anything excessively strenuous until ~1/2 a year of climbing consistently (2-3 times a week). Until then, focus on climbing while trying to keep your center of mass as stable as possible, particularly when moving from one hold to another. Very few typical V0-V2 routes require a lot of dynamic movement to reach the next hold if the proper technique is applied to the move.
Another thing to focus on is reading your route and executing it. If you're physically fit, there's a tendency to just muscle through the lower graded routes since you can without applying the techniques to do the route without using the techniques that the setter was putting in the intended beta. If you're stuck on the V3 plateau (which is reaaally common, so don't get discouraged!), try doing the routes you can do using as little effort/strength as you can and try to force yourself to use those intended techniques. It will help you become more aware of the toolset available to you in particular situations and work out the muscles necessary to execute those techniques that are actually required for being able to send more difficult, complex routes.
Correct. This post and all replies are only local to the lemmy.world instance/server. Since Beehaw isn't federated with lemmy.world, it also means that other instances can't see anything here since this data never makes it over to Beehaw and the data for all instances that do federate with Beehaw will only pull the data contained on the Beehaw server. At least, that is my understanding of how the technology works.
