Sometimes you don't want to be the reply guy within a post that has sparked something within you. I've quoted a post a time or two because of that.
Someone's going through something and they don't need my story to pile on their thread. I'll make a short supportive comment and a boost. Then I will screenshot the item and put my feelings into my own time line with that screen shot.
If there's a better way to do this, I'd like to learn.
