Reddit's like a city; Hubski's like a small town. You can get to know people better here and they can get to know you. Things move slower. Circles of friends emerge and sometimes it may feel cliquey. But the upside of that is that your interactions here can be more meaningful than in the big anonymous city.
You might find yourself thinking a bit harder before you post. (Is that article you agree with actually any good?) Don't aim for popularity, aim to make the conversation better. The site's not set up to be an echo chamber. Muting is available but is really a last resort after actually talking to people.
And on Hubski it's kind of normal for people to reveal a bit about themselves. That can feel odd if you're used to sites where people hide in the crowd. The crowd here turns out to be small and relatively friendly. People even meet up, have drinks and post photos of the event. Crazy.
