Thing that gets wet when u rub it You use it everyday

I can be found on the edge of heaven, Or on the side of buildings, I sound like a supporter of animals, and on Reddit I am a source of knowledge. But in the end I gradually fade away

I start at home, I end at work, through streets and rails I twist and lurk. Each day I repeat, yet never the same, A daily ritual with no one to blame.

I speak in clues instead of telling you anything directly. I look harmless until you try to untangle me. I reveal my meaning only when you stop reading my words and start thinking around them. What am I?

I connect teeth, cards, songs, and cities without ever moving. What am I?
