There may be a problem for Facebook when a group of teenagers says it "confuses and scares" them and makes their eyes hurt. Though Facebook is still considered the most popular social network among teens, their enthusiasm seems to be waning.
Some of them blame it on the ads and the games, but they also say it's become too popular with their parents.
A recent Pew Research Center report found that 77 percent of online teens are still on Facebook compared with 24 percent on Twitter, but the latter number is up 16 percent since 2011.

Carl Quintanilla interviewed a group of students from Torrington High School in Connecticut and at least anecdotally, they were on par with the Pew study.
Senior Austin Kelson considers himself a big tweeter.
"One of the things I love about Twitter is that whatever you wanna say, say it in a couple words and that's it," Kelson said. He and his friends say that, in addition to their friends, they follow celebrities, musicians and athletes such as LeBron James.
As reflected in the Pew study, the number of ads on Facebook has been a turnoff to the Torrington students.
But when asked about Twitter's approach to advertising, Brianna Cole said, "The way the ads are done on Twitter I think is actually pretty clever. I mean, they're done in the form of tweets. So it's not something that is an eyesore. It's just another tweet to scroll past."

When pressed, the Torrington kids admit they probably could live without Twitter but Kelson prefers not to. "I could live, but I don't know-I'd be pretty bored," he said.
With teens being the most fickle online users, their current attachment offers no guarantees for the future, according to Cole.
"There was Myspace before Facebook, and then Facebook happened and everybody thought that was the next best thing, and then Twitter happened," she said. "I mean, there's always going to be something."
