Is Facebook using you?

This article is about how author Lori Andrews has noticed facebook makes millions from the advertisments facebook shows us. I think the main point of this article is Lori Andrews wants people to be more careful with their searches because they could lose an opportunity. I don't ever worry about something that I posted online to be used against me beacause i never put anything online so serious I will say to them it to he/she in person or call them. And any feelings i have I can keep them to myself. Facebook uses a lot of advertisements to pull people in who have the need for something that ad and or have had history of buying the like product. After this I am concerned what I do and say online because the future I could lose a job opportunity just for one mistake I made as a teenager. So if there is anything i have to say I don't have to put it online. worry about personal and private messages. sometimes i think like what if somebody find out about these messages or if the person i sent them to will share them. i dont worry about my facebook, twitter, or blog because my post are never personal. i just write little stuff most of the time, as long as its appropriate then im cool.
