(CNN) -- People keep on flocking to sites like Facebook and Twitter, and young women are leading the way.
The percentage of Internet users who are on social-networking sites continues to climb, according to a survey released Friday by the Pew Internet & American Life Project.
In fact, it has doubled in the past three years, the report says, from about 29% in 2008 to 65% this year.
This year's Pew report also marks the first time that more than 50% of adults surveyed (Web users and nonusers) use social networking.
In February 2005, 5% of adults told Pew they used social media.
The report calls young adult women the "power users" of social-media sites.
About 89% of online women from 18-29 years old are on the sites and 69% of them say they tend to log onto social media every day.
Overall, 69% of women on the Web said they use social networking, compared to 60% of all men.
Pew said women have been "significantly more likely" to be on social sites than men since 2009.
Only search engines and e-mail remained more popular than social media among Web users, according to the survey
In one question, Pew asked people who have used social-networking to give a one-word description of their experiences.
The responses were overwhelmingly positive, the report said, with one-in-five being negative.
Among positive responses, the top five were: good, fun, great, interesting and convenient.
The most popular negative responses were: boring, confusing, frustrating, time-consuming and overwhelming.
We're particularly fond, however, of Pew's list of words that were only mentioned once in a survey of well over 2,000 people.
Our favorites? Hogwash, glitches, omnipresent and nosey.
The findings are from a phone survey of 2,277 adults conducted in English and Spanish between April 26 and May 22 . The margin of error among Internet users is +/-3.7 percentage points
