To get a job in TV is just amazing.

I don't want girls to aspire to being famous for the sake of being famous.

I didn't realise until I did CBT that I was a perfectionist. Whenever you do anything, there are always going to be things that go wrong, it's never going to be 100 per cent perfect. Because of how I was, I'd focus on those bits and always see the negative in anything.

CBT really helped me, and I would recommend it to anyone.

I like a challenge. I like doing things that scare me.

In TV, you get so many different opportunities, and especially, you get to try something different you don't get to do as a normal person, then great.

Even though you picture Russians as stoic, their language is really poetic.

Maths is the language of science.

I'm not into bags, so I don't pay a lot for them; I get them from H&M and Topshop.

I am lucky because I often get my makeup done by professionals, and they always try new ideas; I'll attempt to vaguely recreate what they've done.

I'd happily describe myself as a TV presenter now.

If I find a dress I really like and it happens to be a bit short, I'm not going to lose any sleep over it. The thing about going to Oxford is it does give you the confidence to be how you want to be.

When you're out shopping, try to calculate the discount of something in the sales, or work out how much a bill in a restaurant will come to. Your brain is just like any other muscle - you have to train it to make it work faster.

I'm the sort of person who has to learn something properly before I show anyone.

When I see myself on screen, I don't even feel like it's me - it's like it's a completely different person.

My biggest vice? Vegan cupcakes, which are delicious.

I love that once you know the basic rules of maths, you can do whatever you want with it.

Maths is like learning a language: you need to learn the basics to get going, but a lot of adults go into blind panic about numbers and switch off.

Some of the words that pop up on the show have had terrible connotations. But that's the beauty of 'Countdown.'

You can have your opinions, and you can share them with your friends, but why would you go online to tell a stranger something random about their appearance? I don't get that.

I have never been graceful, never been elegant.

I'm really lucky to be in the TV industry and to have a regular yearly contract. That gives me security.

Without 'Countdown,' I'd probably still be a data analyst in London.

More than other subjects, there's a myth that you have to be an absolute genius to be good at maths and to enjoy it, so I think it's less accessible for people. Even the word 'maths' makes people screw their face up. They do the maths face.

There's an ingrained mentality in our culture that women aren't as good. Other places, it doesn't exist.

I'd love to present a popular science programme because it's something I feel very passionate about.

Groupon is a great concept packaged in a superb name, but the concept of group discounts is not new.

Is there anything about the JonBenet Ramsey case that isn't weird and disturbing?

Groupon, as you probably are by now aware, is exactly what it sounds like: a daily-deal site offering group discounts. Maybe you've seen that done before, but certainly not like Groupon, which has executed with an energetic sales force and engaging copywriters, many culled from the Chicago comedy scene.

What I do want is to be transparent about where I am and how I got here. I don't like the cone of silence - it didn't do me any favors in my 20s or 30s, and I don't see it doing much for other women, either.

I started as kind of an outsider - freelancer working from home, building contacts from the ground up etc. - so I didn't have too many relationships holding me back.

What does 'work' mean in this 21st, ultra-wired century, with its exploding new industries, low barriers to entry and endless possibilities? Is technology making our lives more flexible - or our days more endless?

I not only work online through my various projects, but I am an avid user of online technologies to connect and engage with friends as well.

I am a pop culture person. And car people have clearly contributed to pop culture, which is how I knew about purple French tail lights and 30-inch fins without exactly knowing what they were.

I don't mind other guys seeing movies I want to see and then writing about them. That's fine, especially when it's the New Yorker's Anthony Lane, because he knows this stuff pretty well.

Twitter is an astounding platform for information, but it's a total blank slate - which means it's an astounding platform for disinformation, too.

Flying over New Orleans on our approach, I got it. There was no view of land without water - water in the great looming form of Lake Pontchartrain, water cutting through in tributaries, water flowing beside a long stretch of highway, water just - everywhere.

I don't feel like I have to apologize for being a technophile, ever. Technology is awesome and lets me do so much. Nor do I feel like I have to apologize for loving my work.

Jessica Jackley has a gift for making people want to fork over their cash. To total strangers. Far, far away.

Emily Gannett is tireless. I know this because I have traded emails with her at 2 A.M. only to later wake blearily to a chipper morning missive sent south of 6 A.M. before her morning run.

If anyone was going to write the definitive account of what the 2008 election meant for women, it would be Rebecca Traister.

In September 2005, I was three things: the media blogger for 'FishbowlNY,' a maniacal Daily Show fan, and the only person to smuggle a tape recorder and camera into a big Magazine Publishers of America event featuring Jon Stewart interviewing five hotshot magazine editors in an unbelievable bloodbath.

There's a tendency, when the offspring of a famous person does something notable, to define them by their more-famous parent.

Oddly, a search for 'jeggings' in my email inbox shows that my first exposure to the phenomenon came from - wait for it - Mike Allen of 'Politico,' who helpfully explained the concept on December 20, 2009.

My weekends are oases of time and space, where I am able to draw a breath and dive into the stuff I couldn't get to that week - the great article I bookmarked, the friend whose emails I kept dropping, the blog post I'd meant to write on a subject that wasn't timely but was still important.

Reporters do decide what is news, but they don't invent it, even if they sometimes become part of the story by risking their lives in a danger zone, as in the case of ABC's Bob Woodruff and Doug Vogt.

My first introduction to New Orleans was from the air, flying high over the city with a view of the land - and water - below.

If you don't know Tom Lehrer, you should - in addition to being a classical pianist, mathematician, songwriter, satirist, researcher at Los Alamos and, he claims, inventor of the Jell-O shot, he is just delightfully funny and graceful.

I downloaded a Ricky Gervais podcast once at the persistent urging of a friend and found it funny but distracting - if I'm online, I'm surfing, which means I'm distracted from the podcast. So it's a form that doesn't really work for me.

If there's one thing that 2009 showed us, it's that everything is happening everywhere, across multiple platforms, each one making waves that end up crashing against each other and commingling into one giant media sea.
