I used to walk, but now I'm cured, So you won't have to chase me. I come from someplace smoky, And you just can't wait to taste me!

Poor people have me, rich people need me, and if you eat me, you will die. What am I?

I resemble the sound of a thud, but I am not made of wood. People describe me as something they need more of.

I spread like a sneeze but never get sick, I’m born from a joke or a clever old trick. I change my clothes but keep the same face, I live on the internet, all over the place

Up I go, and your post gains fame, A tiny click, a big online claim. I'm not a comment, a share, nor a save, But I show I like it, and help it behave.
