I too came from Reddit, be sure to check out the FAQ and the Site Rules as this site differs from what you may be used to.
This community is warm, welcoming, and very friendly. The attitude here promotes kindness and civil discussion. A good example of this is how the down vote arrow is used. Down voting is reserved for content that violates posting rules, is spam, or is not relevant- it is not a tool to signal dislike/disagreement. The community here does not ignore this rule and takes it very seriously.
I am sure you will love it here, thanks for saying hello!
