Welcome to Steem! I love a bit of scifi, so I'll look out for your posts.
A couple of things I would recommend:
- There are various ways to use Steem. I would recommend @Steempeak and @esteemapp, but there are others. Get the Steem Keychain browser plugin as that makes it easier to manage your keys whilst keeping them secure.
- Here's a beginner guide by my friend @slobberchops.
- People like to see some proof of who you are. You could link to your Steem account from another social platform you use. A video of you saying who you are is also good proof.
- Find people who share your interests and connect with them. Some people seem to forget this is a social platform.
- Have fun!
