One thing you'll notice here, that's significantly different than other social media, is that people spend an inordinate amount of time building each other up. It's a stark contrast to what you see on any other social media. You do something awesome? people will invariably upvote it and share it with their friends.
The rules you talk about are largely unwritten, but moreso enforced by the community. The big one that will get you hit with lots of downvotes is plagiarism. Original Content is king here. If you're talking about yourself or something you think is cool, people will notice.
Also, @acidyo is good people. Though I'm sure you already knew that.
Also also, welcome to Hive!
Yeah, and people are super helpful. I was delegated 30HP because I had not enough resource credits to post. That does't happen everywhere.
I plan to make more original contents and eventually contribute something to the platform like you guys :)
Thanks for the warm welcome
