Is virtual life isolating people in smaller worlds?

Since the advent of Internet people are more often showing themselves through a computer screen than socializing in public with friends and family. One of the main reasons leading to this behavior is that individuals don’t need to “come out” and be in situations which can cause harm or embarrass them. Embarrassment can restrain, but this restriction, or reservation, happens for a good cause for many. Having a computer helps a whole lot socializing, but is it healthy socializing only virtually?
