Welcome! There's a bit of a learning curve but the best thing you can do is comment and make friends on the discord chats and post stuff that's fun for you cause rewards correlate with engagement and relationships as much as quality.

Powering up makes your vote worth more and shows people you are committed to the ecosystem. Not necessary but it allows your Hive to actually work rather than be just a plain currency.

If you have any questions feel free to ask 😃. You can search for posts about different topics too.
