(CNN) For the sake of this story, I'd like to invent a new acronym: IAVS, which means, "I am very sorry."

The reason for the apology stems from a story I wrote last year, "28 Internet acronyms every parent should know."

"Wouldn't it be interesting to do a piece on the acronyms that teens are using across the Internet, especially on social media and apps, to help parents understand what, in fact, their kids are talking about?" I thought.

Even though I was at school, I would still check my phone because I mean, people post things at school and stuff, so you still always worry."

"The most times I check it (my phone) in a day? I lose track. It's just a need. Like I need to."

"I definitely feel pressure to look perfect on Instagram. What goes through my mind as I'm posting a picture about myself is - I'm thinking, ˜What will people think of this? Are they going to approve? Are they going to think I'm ugly, are they going to think I'm pretty? I'm thinking all these things and I'm comparing myself to others."

"I like made this google document on all my rules and requirements on how to take a selfie. I take a lot of pictures, but don't judge, I take like 100 usually, or like 150, maybe 200 sometimes if I really can't get a right one.

I consulted existing lists of Internet acronyms and talked with Internet safety experts. It seemed fine -- until the story published and I received a wildly critical response on social media, often with language that I can't include here.

My Twitter feed blew up with people saying I didn't know what I was talking about and that teens weren't using most of the acronyms on my list.

Here's why I'm sorry: For that story, I never consulted with the true experts -- teens, themselves.

I'm thankful to have a chance for a re-do, and this time I know we'll get it right because our list comes straight from the social media posts of 13-year-olds around the country.

As part of a two-year investigation, #Being13: Inside the Secret World of Teens, Anderson Cooper and his "AC360°" team connected with 200 eighth-graders at eight different schools around the United States. They, along with their parents and schools, gave CNN and two child-development experts permission to review what they were posting on Instagram, Twitter and Facebook over a six-month period.
