Social Networking,Privacy Issues

Let’s imagine our lives without the services of online chatting and mailings.
Would have been damn boring to realize that we are not even connected to our friends or maybe someone from whom we could learn something at time of emergency: sitting in the office maybe!!!
These blogs, chat rooms and chat friends have gained so much importance in our daily lives that, we have developed a habit of it.

Social Networking Online relates to formation of a circuit or a chain of friends, family or partners who use variety of tools to interact with each other or share their views in accordance to different aspects.
A proper definition of Online Social Networking can be given by "a community of people who share a common link and thus connect to each other through their social interests, social media or any other needs and thus bond together using social netowkring sites and portal service."
Most social networking sites allow you to create a profile - a section that tells others about you. While many of these are personal, they can also be used for a business that is posting to the site (if the site allows this).
Profile allowances are different on different sites, and many limit the amount of text you can provide in different areas. When this is the case, they may indicate the character limits for an "input text box" and some may even count and display the number of characters used, or tell you how many are left. Others do not. What happens is that people rush to sign up for the social bookmarking sites. They register and mindless begin filling out their profiles, sharing lots of personal information like date of birth, complete name and contact information / location (email, phone number, personal photos) and more. However, people most often don’t use the privacy settings offered by the sites, as they should.
Example of social networking site is youtube,
…and we know a lot of other people watch [YouTube] like our friends, and it's — if we wanted to tell our friends, "Hey, come and watch this," it'd be a lot easier if we just put it on YouTube instead of sticking it in an email and waiting for the email to get there and waiting for them to open it which would take forever 'cause the file was so big. So we just put it on YouTube and go the link, sent the link to everyone, and they watched it.
