Welcome; Follow people that pique your interest. Don’t follow people for popularity reasons alone. Post honest content, positive where possible. Remember you own what you post and it’s permanent so be courageous and thoughtful. Engage lots, zap when you are impressed. If you do object to something - engage the idea, not the person who made it. Be willing to say sorry if you regret something you said. In short engage using civility as if you are with a person in real life not some online anon. Enjoy and learn!
