Nothing wrong with that imo. If you don't like it, just use another instance.

This system means people can foster their instances to be however they want, and that's great!

Also, fyi, if you're on lemmy.world, leave any beehaw comms you've joined and join alternate comms in other instances. The beehaw comms are going to be very empty on your end soon.

Not any that I know of. Doesn't matter much though; there's no karma system here to worry about, and you only really need one account on an instance that doesn't block others and isn't defederated by most (like lemmy.world or lemmy.ee) as long as you don't join beehaw comms.

You can check if an instance is blocking any others by clicking 'instances' at the bottom of the page.

This beehaw thing is very rare. Just stay away from the instance and its comms for now until lemmy's improved further to support this massive wave of users.

Is kbin a good place to set up shop? I don't really understand the advantages/disadavantages of different instances. I made an account on lemmy.world first, but I remade me account on kbin a few hours later because I like the kbin interface a little more.

Also, if there's no karama, what are the "reputation points" in my profile?

I prefer Kbin over Lemmy because it feels like old reddit, and the magazines are a lot more like checking my subreddits than others. It's also not currently defederated with anything, but it's worth noting that could change at any point. Kbin is the fastest growing of any of the instances atm,

At the end of the day, the whole fediverse thing means, within reason, it doesn't really matter where you set up shop.
