Totally agree. Basic rules that I follow are:

1. Don't say anything (comment or post) if you don't have anything positive to say
2. Do research before posting and learn in process
3. Respond to comments - it is more enriching this way
4. Don't be a police for steemit - not your job. This is how social media works
5. Remember that whatever you post, is recorded forever!
