Here's a rewrite: I don’t really see the cons of Facebook, or maybe I just don’t consider them as cons. I think that every person who has a profile on Facebook needs to realize that 300 million other people also have one, which may include your current boss, ex-girlfriend, a policeman, or any other law-abiding person for that matter. With that in mind, one should be more careful about what things one posts on Facebook. For example, if you told your boss you won’t be coming for work for a couple of days because of a family matter, but the real reason is that you wanted to go to a one-off Halloween party, then it would be wise not to post any pictures of yourself at the party on Facebook. Moreso if you have your boss as a friend on Facebook, who no doubt will soon discover your little lie. General points: - 3rd-person verb format when using "one" (eg. "things one posts on FB") - keep the pronouns consistent when telling a story: you switched from "you"(2nd person) to "the worker"(3rd person) which made it sound like you were talking about two people instead of giving an example to your reader. - re. Emily's point about splitting up the last sentence: if you're using a lot of commas, some of them should probably be full stops. - I cut off the very end, as you'd already given all this information.

every person who has a profile on Facebook NEEDS to realize policeman instead of policeworker law abiding citizen instead of law obedient person With that in mind, one should be more careful with the things one post on Facebook. (new sentence) If you said to your boss... The last sentence is very long and I'd suggest splitting up the ideas into separate sentences and making it more concise.
