YouTube challenges, hashtags and other digital trends spread like wildfire among the group of children who are in that magic, impressionable age between grade school and high school. Most digital trends are harmless and quickly forgotten; some can be positive, and some are downright bad news. 

As 2014 winds down, now is a great time for parents to reflect on the year's top digital trends. Here is a glimpse of some of the biggest online fads from the past year.

Social Media is Still King. But Which Networks?

Facebook has long lost its groove among those younger than thirty. A social media network where Grandma might leave a sweet message for everyone in school to see isn’t where kids want to hang out. Newer networks like Instagram, Snapchat, Kik, and Vine have blossomed in teen popularity towards the middle and second half of 2014.

Have a gaming teen, tween or child in your household?

Parental monitoring and involvement is critical when it comes to helping children game safely. You should take an active interest in the games that your child plays and wants to buy.

We also suggest that research game ratings and content on www.esrb.org. This website is maintained by the Entertainment Software Rating Board which rates thousands of games each year.

See what measures that middle school administrators are taking to exterminate a dangerous new trend that is circulating among students. This article was originally published on the Huffington Post and is written by Rebecca Klein.

Students at one Connecticut middle school aren't using pencils solely for taking notes. Some are rubbing their arms with pencil erasers until their skin is mutilated.

School administrators at Bethel Middle School recently sent a letter home to parents and guardians asking they talk to their children about a dangerous game called the "Eraser Challenge."

The game, the letter explains, involves kids “'erasing’ their skin while saying the alphabet and coming up with a word for each letter. Once they get to the letter Z, they stop and then compare the injury to their [friends'],” according to the Bethel Patch.

There is a new app on the block for Android and Smartphone users. The app, Yik Yak, allows users to post anonymous comments and thoughts. The app also takes into account the geographical location of the phone, using the location services of iPhone and Android phones to feed users comments that have been posted close by. The purpose of the app is to start anonymous conversation, but in the age of digital parenting it can be seen as far more sinister. 

Yik Yak and It's Growth 

Yik Yak debuted on Google Play in January of 2014, and entered the iPhone market in December of 2013. Since its introduction to each platform it has grown quickly. It is currently listed as the 70th most popular social networking app on the Apple App store. It has been downloaded over 6,000 times from the Google Play store and is growing by 38% each month. The free application offers young adults a platform to comment and chat anonymously with those around them. Because the application uses a phone's location services to find where the comments are being posted from, it also allows users to see comments from people that are close to them, often within a few blocks or even feet from them. The location aspect of the application has made it increasingly popular with young users, specifically those in middle school and high school, even though the application insists it is only intended for people over the age of 17. While the application restricts the age, in theory, the entire interface is skewed towards young users, with a colorful interface, cartoon-like graphics, and an easy to navigate platform. 

Yik Yak's Policies and Guidelines 

According to the rules and regulations of Yik Yak, users are to be aged 17 or older. Bullying, according to the app developers is strictly prohibited, and users are also prohibited from posting full names and phone numbers in their comments. Inappropriate content can be tagged for removal, but opponents of the app claim that content is not being monitored, nor are the users that are currently logged into Yik Yak. If someone wishes to have inappropriate comments removed it can be done in one of two ways;

• Two users can flag the content for removal. If two flags are received the content is removed.  

• A single user can send a screenshot to Yik Yak and the team will consider the comment for immediate removal.
