If the post has great information and I think other people, especially minnows, can benefit from it then I resteem it on my account. I could care less if I earn from it or if the person resteemed something of mines back. I do simply because it's great information. Great info is just that, and if it's gonna help others, why not...? I don't aspect anything in return because I feel that it sets a person up to let themselves down if things don't go the way that they want.
