How important has Internet become in our lives? The Pew Research Center conducted a survey to celebrate the Web's 25th birthday. The researchers were greatly heartened by what they found.

"In 2006, only 14 percent of American adults used Internet. Today, it's 87 percent," said Lee Rainie, the director of the Pew Research Center's Internet Project. "It is what has impressed us the most."

The survey also showed that 70 percent of the Internet users have been treated kindly or generously online while 25 percent of respondents said they have been treated unkindly. More than half—56 percent—of users said they've seen an online community come together to help someone solve a problem. 25 percent said they've left an online group because members were too unpleasant.

When Pew asked questions about whether being online has enriched people's relationships—or not—the results were very positive: 67 percent of Internet users said their online communication with family and friends has generally strengthened those relationships. Only 18 percent said it has generally weakened those relationships.

According to the survey, 53 percent of Internet users said Internet has become the hardest tech tool to give up. It is 15 percent higher than the result of a similar survey conducted in 2006. In fact, more people said they would have a harder time stopping using Internet than giving up TV. (These days, so much great television streams across the Internet that it makes sense.)

"In our survey, we have found that the Web makes a few people very unhappy. There's strong evidence pointing to the fact that Internet users tend to compare their daily lives with the ‘highlight moments' of their friends' lives," said Lee Rainie. "It's really silly."
