Which statement about social networking is true?

it’s important to use correct grammar and punctuation in posts.

it’s smart to friend as many strangers as possible to widen your network.

posting about your vacation while you’re there you stay in touch.

you should never post anything you wouldn’t want a potential employer to see.

Definitely the last option is the one who is very true. In order to be safe regarding social networking you should never ever post something an employer would see in an interview. That would be very bad for your professional profile. The rest of the options are actually unsafe practices for social networking or not essential for them, like the first option. Hope this helps
