MOST of us have an online identity or three.
You've got your Facebook, your Twitter, your Instagram - and even your Pinterest selves.
You might also be part of a football chat room, a dating website, or a business community.
Through all these cyber outlets you can choose what information you give away and how you want to be perceived.
What surprises me is how different people come across on the internet compared to real life.
For example, you might overshare cat pictures and drunk updates on one site, while the others are for professional posts.
And it's your cut-throat self that rears its head when it comes to Ebay.
I've got no shame in playing the dirty last-minute bid card for a coveted-coat - but I'd never push in front of anyone in a shop.
There are close friends who I can't stand in the cyber-sphere.
I don't even recognise them as they boast about their new designer handbag and their amazing life, which in reality is no more special than anybody else's.
Or when they go on a rant or sprout out pointless opinions about celebrities: nobody cares what you think about the Solange/Beyonce/Jay Z CCTV footage.
The easiest solution would be to abandon these sites and not go on the internet but it's a big part of our lives.
Luckily there's a way to get round this without hurting anyone's feelings or causing a stooshie.
Twitter is rolling out a mute button which allows you to hide a user's Tweets from your timeline.
It is similar to Facebook which has its own hide option to neatly make people disappear from your view.
Muting is perfect for hiding an ex-partner's feed, an old school friend who you have nothing in common with, and people who post incessantly about the Eurovision Song Contest.
You can banish them with a click and then bring them back into your life whenever you feel ready - and they will be none the wiser.
In fact they might actually be getting rid of you at the same time.
Although this careful editing of people seems a bit like something a North Korean dictator would do, I think it's a useful tool.
But when it comes to the darker side of the internet, which is far worse than one annoying tweet, we need more action.
The curse of online bullying came flooding back to me last week during the BBC documentary, Blurred Lines: the New Battle of the Sexes.
Kirsty Wark examined misogyny in the internet age and interviewed women who had experienced the full force of Twitter, including rape threats.
These people don't just need to be temporarily hidden, they need a permanent mute button.
I would tape up their mouths and ban them from the internet altogether.
