When you were in university, posting that video of you doing an epic keg stand was cool. Now that you’ve finished law school and are looking for a firm to join — not so much.

Do you remember what you were doing and thinking at this moment last year. What about five years ago? A decade? If you can't perhaps you tweeted something or made a Facebook post? Yesterday, a pretty momentous moment in my personal history popped up on Facebook - the day I bought a new house in the morning and sold my old one the same afternoon - and I remembered the feelings of excitement and relief. And then I thought about James Gunn, the recently fired director of the Guardians of the Galaxy franchise, and the cost of old tweets on his career.

Most of us know we spend too much time on our phones. It’s led to a host of studies on the negative effects, and there are definitely repercussions to constantly peeking at your notifications and following those digital squirrels at every chance you get.

Twitter has been working hard to clean up their game. Following an account purge, to get rid of fake accounts that have been used to spread misleading links and information, and efforts to remove users that make abusive comments using the comnay's video broadcasting app, Periscope, the company has taken a beating on the sharemarket.

It's fair to say Facebook has not had an easy time of it recently. They've faced the Cambridge Analytica scandal earlier this year, lacklustre appearances by CEO and Founder Mark Zuckerberg in front of inquiries in the US and EU, and continuing allegations of how the platform was misused to influence the 2016 US presidential election. And the news hasn't improved. Here's what's happened to Facebook this month.

It’s harder than it used to be to accidentally lose all your work. Apps come with auto-save, and Chrome tries to warn you before you close a tab with unsaved work. But hit enter too fast, or suffer a crash, and you could still lose a lot of writing. It can happen to a Facebook update, an application form, or a blog post.

Social media stalking might be creepy and a waste of time, but most of us are guilty of it at one point or another. That's why, after our latest "How to hide your accidental 'like' on Instagram" post, we were intrigued by this even more efficient tip coming from one of our readers.

A dad named Jack R. says just about every week, his 9-year-old son asks if he can use the app Musical.ly. His son's best friend has been telling him that everyone at school has an account. After hearing the kid beg all summer, Jack finally decided to download it onto his own phone and sign up himself so that he could look into the privacy settings and "see how stranger-danger it was."

When he entered his gender (male) and birthday (he's 32), Jack says he was bombarded with content he never expected.

For someone who writes for a living, my Twitter feed has an embarrassing number of typos. I typically notice them the second after I hit post and am immediately faced with the decision "Do I delete this tweet and pretend it never happened or just roll with the typo?"

Keeping up with your friends on all the various social networks you share can be an organisational pain. Now, however, Facebook is making this a tiny bit easier by allowing you to bring your Instagram contacts into Messenger, which also syncs your Instagram and Messenger conversations.

If you're tired of seeing all of those "on this day" posts on Facebook, you're going to hate Facebook's latest update. The social network launched a new Memories page this week, essentially an expanded version of its "On This Day" feature where you get the pleasure of reminiscing about that burger you ate one year ago today or that time you posted that drunk selfie.

If you’re still an active Twitter user, and if you’ve been collecting followed accounts for years until your timeline became an unreadable mess, you might fantasise about burning it all down. “It” meaning both the entire sinful world and your Twitter feed. We can help with the second one.

Being online has never been more embarrassing. People are renting 10 minutes of time on private jets for the 'gram. The most innocuous and best-meaning of posts can spark outrage. You can't talk to someone on a plane without it becoming a viral story that leads to harassment. The president tweets.

Taking someone’s photo without their consent and posting it on the internet is a crappy thing to do. It’s invasive, inappropriate, and can even put the other person in danger. In a world that made any sense, this wouldn’t require further explanation. This would be a commonly understood part of the social contract.

Whenever you meet someone at a networking event that you’d like to chat with again, the question arises: How?

We've all have a few topics that pop up regularly in our Facebook News Feed we'd rather not see. Maybe you're trying to avoid World Cup details until you get home to watch that morning game on your DVR, or you've finally reached a breaking point with political conversations and want to pretend Turnbull doesn't exist for an afternoon. Whatever your reason, now you can mute those topics thanks to a new Facebook feature called "Keyword Snooze".

I once briefly dated a guy whose entire Twitter feed was about biking. He spent his day posting links to cycling routes, talking about his bike, communicating with other biking enthusiasts, advocating for cyclist safety efforts, and putting up photos of cars obstructing bike paths. All of this is admirable, of course, but the problem was that I didn't have a bike, like to bike, or care very much about biking at all.

Over the last couple of years, we've seen social media tools significantly change the way our feeds are represented to us. It's a source of frustration as it can make finding an interesting post hard to find again and we miss things that happen when the algorithm decides for us that the item isn't something we'll engage with. Instagram has revealed what they do to manage our feeds. And while the make it all sound like it's in our best interest, that's not always the case.

This week, password manager Dashlane analysed ten years' worth of passwords from public data breaches. The big lesson is, don't reuse passwords. Not even a little, not even with a "formula". Password formulas are easy to hack. And even your bullshit accounts deserve strong, unique passwords.
