The beautiful thing about all this federation is that you can jump over to a different instance and up/downvote to your heart's content. I'm currently viewing this thread from kbin.social and I have the option to upvote, downvote, and boost. Several comments have at least one downvote.

The biggest thing that's irksome is that you can't currently transfer your entire account (subs, saved things, etc). You just have to make a new handle elsewhere. I hope that this changes eventually.
