Im writing a 5 paragraph essay about social media

Social Networking makes it possible to reach many people in a very short time. This has led to the creation of a site that is involved in helping the community. Sites like Linked are dedicated to helping those people who are hunting for jobs. Candidates create their resume and CVs and upload them to these sites. Employers just need to make a search of the qualifications that they are interested in. They can also advertise for jobs on these sites and be sure of getting highly qualified persons. Social sites have also been involved in social care by spreading the news in cases of danger. Messages on these sites get to many people in a very short time and this greatly helps in saving many people from potential danger.

The First Paragraph on facts about social media like popular social media sites and etc
Second paragraph should be on why people use social media
Third should be what impact does social media have on people in today's society
Fourth Should Be What You can do using social media
Fifth paragraph should just summarize your 1st -4th paragraph
