These People will probably end up critiquing you're essay so try and keep it a little interesting. Note the vacant expression on the farthest man's face. If you don't want a bunch of lazy people commenting or sleeping on your essay you have to make the intro and the last paragraph really good. You might want to add a lot of pictures and random diagrams to get your point across. You don't even really need to make the related to the essay itself as long as they look professional. Scroll down to see some random diagrams and pictures. These pictures make the reader feel important as if they can understand what the essay is about. So keep these things in mind and your essay will not suck completley.
