From a snow-crested corner of Alberta, Canada, Kelly Oxford made her Hollywood screenwriting dream come true.

From a snow-crested corner of Alberta, Canada, Kelly Oxford made her Hollywood screenwriting dream come true.

She did it without leaving her close-knit family or giving up her free nationalized health care. She did it without toiling in L.A. coffee shops or confronting painful rejections.

She did it 140 characters at a time.

Oxford, a suburban housewife and mother of three, is a Twitter superstar, with more than 350,000 fans. Oscar-winners, late-night talk show hosts, even film critic Roger Ebert follow her on the social media service, eager to read wry observations about daily life and celebrity culture.

"The worst part about having kids is that they magnify every single thing that's wrong with you. And they wake up early."

"If you have a taxidermy marlin and you've never tried to joust someone with it, you're wasting everyone's time."

Those are a few of the 2,900 tweets she's sent since she discovered the medium three years ago.

NBC hired Oxford to write a pilot last fall, Harper Collins will release her first book of essays ("Everything's Perfect When You're a Liar") next April, and in April she sold her first movie script to Warner Bros.

It's about a pot-smoking young woman suddenly confronted with the prospect of motherhood.

Her success points to an appetite for humor from a female point of view. But unlike stars such as Tina Fey and Kristen Wiig, who honed their craft in the "Saturday Night Live" writer's room, Oxford found and shaped her comedic voice in online chat rooms and blogs and on Twitter.

"She's just funny, very consistently and solidly hilarious," said comedian Jimmy Kimmel, who befriended Oxford after following her on Twitter. "It's heartening to know that somebody with nothing other than the quality of their tweets can become very popular and actually make a living as a result of it.

"It's like Twitter was invented for Kelly Oxford."

Long before the advent of social media, Oxford, 34, yearned to share her stories with the world. The child of two hippies dreamed of having her own public access TV show, and she loved taking trips on her uncle's house boat, as long as she could operate the CB radio.

When she was 8, Oxford created her own newspaper filled with reports she invented about her lower-middle-class neighborhood in Edmonton.

In high school, her love affair with writing took a back seat to adolescent flirtations and a few part-time modeling gigs. She dropped out of Mount Royal College in Calgary after one semester; her professors, she says, were more interested in teaching her to write like famous authors than in helping her cultivate her own voice.

She tried a screenwriting seminar but realized that at 19, she had no life experience to draw on.

Oxford waited tables, sold shoes and had a baby at age 23 with her boyfriend James, an environmental engineer. She didn't go back to work after her daughter Salinger was born. Instead, she spent time in chat rooms as she got used to life as a mother.

In 2002, she launched an anonymous blog, posting daily, short stories about her adventures in motherhood or rants about the world at large. Nothing was off-limits.

Her confessional style generated lots of comments. Soon, she had struck up email relationships with those readers, and they championed Oxford to their friends. Before long, thousands were reading regularly and had signed up to receive email alerts any time Oxford posted something new.

"I was so happy ... knowing that every time I wrote a blog about my kids or whatever, that there were 7,000 people excited to get an email," Oxford said in a phone interview late one night from her home in Calgary. "That was enough for me."

Oxford used MySpace and Facebook the way a comedian uses small clubs — as a place to try out material. Twitter made her irreverent humor accessible to the masses.

"Daughter in Gymnastics equals 1% chance she'll be an athlete. 100% chance she'll be the drunk girl doing backflips in a bikini."

"Twitter is like the back page of 'Tiger Beat,' where you found celebrities' addresses and you could write them a letter," Oxford said. "On Twitter, all the celebrities and producers and writers and directors were there. You didn't have to write them, but you could see what they were thinking about. It was suddenly an even playing field."

Not only did she cultivate her own online celebrity, but celebrities began to take notice of her.

First it was screenwriter Diablo Cody, the blogger-turned-screenwriter who won an Academy Award for "Juno." Then it was singer-songwriter John Mayer, who brought Oxford to the attention of his own Twitter followers. When Roger Ebert started retweeting her riffs, Oxford's fan base expanded further.

"She speaks honestly from her own experience," Ebert said in an email. "She can be funny and some of her tweets are snarky, but there's a person there, leveling with us."

Enchanted by Oxford's voice, Emmy-winning screenwriter Jhoni Marchinko encouraged her to write a pilot and offered to serve as her mentor.

Oxford stays up late most nights to write at a cluttered desk in her second-story bedroom in her home in Calgary. A bulletin board near her head is covered in children's art and baby photos of Salinger, now 11, Henry, 8, and Beatrix, 3.

Her fingers race across the keys of her MacBook Air while her husband James — they married in 2007 because Henry became enchanted with the idea of being a ring bearer — strums his guitar a floor below.

In addition to making final revisions on her book, she's rewriting her screenplay, "Son of a Bitch," which Oxford says is about a young pot-smoking party girl with a legion of loyal online followers who must reconcile her new motherhood with her online persona.

Now, when she travels to Hollywood, she stays with Kimmel and his girlfriend Molly McNearney, co-head writer on his ABC talk show "Jimmy Kimmel Live!" They've opened their Hollywood Hills home to Oxford, and lent her a car.

Now, Oxford is preparing to transplant her family to Hollywood for a six-month trial run.

"My weirdest friends are there," she said.

Her agent, Cliff Roberts, said he isn't worried that her impending relocation or her higher profile will dull her edge.

The tone of her tweets certainly hasn't changed. In a recent one, she asked her followers, "How do you get a red wine stain off a baby?"
