So what exactly happened with Hive?

https://peakd.com/communityfork/@hiveio/announcing-the-launch-of-hive-blockchain

Do we get the tokens like in all major forks?

Yep, equal to what you had on Steem when Hive launched.

How does this affect the content creators?

Post on Hive, we're all there. You can post on Steem too, but a lot of people aren't curating here anymore. It seems pointless to add content to a fucked up platform being run into the ground by the idiot who bought Stinc.

How do you move to the new platform or just make a new account?

Use https://hive.blog if you like steemit.com although https://peakd.com, the Hive version of SteemPeak, is pretty nice.
