But can I comment and reply in other instances? If that's true then I guess who cares?

Why would anyone want to do this? If you want to read Reddit just go to Reddit. I'm here because Reddit sucks

I don't understand why you would do this? If you want to browse Reddit just go to Reddit

No aggregate all feeds from all instances?

Just check how unfunny their post was. If it is certified not funny: German. If it's the worst attempt at humour you've ever seen in your life: Austrian

Exactly, so who cares if some bots stop working? Not the users.

Actually I think the whole upvote system sucks. I prefer 4chan, every comment is equal and people just ignore dumb shit. The upvote system promotes popular opinions and discourages saying anything that remotely goes against the flow. It's what made reddit such a echo-chamber circle-jerk place.

Why? Who reads over 6000 tweets a day?

Everyone thinking Germany is their best friend surely can't end badly...
