When I finished Grade 11 in June, I reflected on what I had learned in the past school year. I was taught how to solve quadratic equations, the origins of world religions and studied the Canadian Charter of Rights and Freedoms. Oh and I know the legal requirements of marriage! But there was something I wasn't taught. Scrolling down my Twitter timeline, it hit me -- why was I never taught anything about social media?

Snapchat, the mobile app that lets users send "self-destructing" photos, has the distinction of being the only digital tool that does not have a single redeeming feature. While the moral panic associated with blogs, cell phones, social networks and online games has largely faded in grudging recognition of their more positive uses (indeed, research shows that many parents have actually helped their children lie about their age register for Facebook accounts), Snapchat is seen as the Q-tip of the digital age: its sole function is to do the thing that you're warned not to do on the box.

We generally think of our kids’ online and offline lives as being two separate things. In reality, they constantly overlap, flowing back and forth face-to-face in the schoolyard and through texts and social networks at home. But on the Internet there are lots of moral and ethical choices that don’t have to be made offline.

I’ve already written about YouTube and Instagram, but today I wanted to share some information about four other popular sites and apps that are on my radar right now: Snapchat, Vine, Tumblr and ask.fm.

Is technology drawing us closer together, or pulling us apart? When it comes to TV and digital media, the answer may well be "yes" to both.

How #Ottawapiskat turned the tables on media coverage of native issues Over the last few months the Idle No More movement has succeeded in bringing Aboriginal issues to national attention. This has been due in no small part due to the movement's use of Twitter, where #IdleNoMore was a Trending Topic in both Canada and worldwide.

Like it or not, if you use the Internet you have an online identity. Some people call this your "brand." What's a brand?

It's been a busy few months for Facebook: a government investigation, another in a seemingly endless series of changes to the site's privacy controls, a New Yorker profile of its famously publicity-shy founder and the upcoming release of The Social Network, a thoroughly unauthorized account of its early days. With all of the publicity and controversy around Facebook – not to mention its still-growing popularity – it's almost impossible to remember what online life was like before it. In fact, it's not much of an exaggeration to say that those who began using the Internet after the introduction of Facebook and its competitors do so in a way that is fundamentally different from older users.
