In my opinion, Internet is one of the greatest people created. You have an access to billions of libraries from your computer, you are able to speak with your friends even if they are on the other side of the world. Many people work using the Internet. Now let's mention disadvantages of the Internet and web-technologies. Firstly, many people nowadays become addicted and can't survive for more than an hour without computer or smartphone. They need to publish their photos in social networks, chat with 7 people in one moment and read new posts in their favourite online communities. Young people sometimes find their online-life better than the real one. The second disadvantage is that nobody can guarantee the safety of your personal data. Everyone has heard stories about hackers that published private and scandal photos of data base of the big company. It's not really pleasant to know that somebody can easily find out all your secrets. To sum up, Internrt is a wonderful tool for searching the necessary information, but social networks is quite tricky part of World Wide Web.
