I suppose one can make more leaving comments than making posts...
@pocketechange

some people play it like that. Some do the resteeming.

How do you resteem?

you pick a post and click on the resteem-button.
The resteem-button is on the left side of the Reply - "Button" (under the post).
It looks like an arrow.

Thank you, i did it on this reply. And so, what does resteem accomplish?

It's basically the same as sharing a post.

Ok, so the people that follow me will see that post on their feed?

It shares the post on your blog.
