Due to persistent power outages and failing phone lines, she was unaware that two days earlier she and 18 others had been listed as candidates for the £30,000 award.
"I was walking on air," she told Al Jazeera.net when it finally sank in.
Riverbend, who describes herself as a 26-year-old computer specialist, insists on remaining anonymous.
Riverbend's blog Baghdad Burning began to make waves in late 2003 and quickly became one of the most read Iraqi blogs. She offered an Iraqi woman's perspective on the US invasion and the first months after the fall of Baghdad.
Since then, her blog has been adapted into book form by UK-based publishers Marion Boyars and New York-based Feminist Press.
In March 2005, the blog was adapted into a play by a New York-based theatre production company.
Commenting on daily political and sectarian strife and "life under occupation", the blog has also won third place in the 2005 Lettre Ulysses Prize for Reportage and a 2006 Bloggie award.
The winner of the Samuel Johnson prize will be announced on June 14 in London.
Al Jazeera.net: How did you react when you heard of the nomination?
I was surprised. I actually thought the BBC online article "Iraqi blogger nominated for prize" was referring to someone else. Then I checked my emails and found my British publisher confirming it. I was ecstatic.
The nomination is for the book based on your blog. What inspired the blog? Was it your intention to adapt it into a book?
Another Iraqi blogger, Salam Pax, whom many consider the father of Iraqi blogs, inspired me. I guest blogged a couple of times on his forum and he encouraged me to begin one of my own.
"As an Iraqi living abroad, I'm proud to see an Iraqi woman from inside telling the things we all would like say to the world, especialy in these difficult times when truth is a very rare thing to hear."
I never thought it would be turned into a book even though I got several offers within a few months of blogging. I didn't like the idea of turning the blog into a book at first because all the publishers wanted me to discontinue blogging. Feminist Press is the first publisher that didn't want me to stop blogging.
Iraq inspires me to blog. While I began blogging as a way to vent frustrations and fears about the instability and insecurity, I continue because I feel the media covers the situation in my country in a very general way.
Many articles don't even begin to touch the daily reality Iraqis face.
What are the realities that you feel are not reported?
Real Iraqis, the people currently suffering under a lack of security and a shortage of the most basic necessities like electricity and water, seem to have faded to the background while the media is busy with the failed attempts of the current government to organise themselves.
I'm also frustrated with the way the media oversimplifies certain situations - like the sectarian violence being promoted by the occupation forces and the current government.
Some have suggested that your blog is an important part of documenting history in the making. How do you react to that? Was that your intention when you started it?
I'm very flattered, and somewhat awed, with that description. I began it tentatively, not even sure anyone would actually read it. To say that it is "an important part of documenting history" is beyond any description I ever imagined when I first began.
I believe all blogs document history - just different chapters in history.
But some of your detractors online have said you are unabashedly biased and anti-American and that you lament the ousting of the previous government. Is that true?
Unabashedly biased towards what? Iraq? One thing that bothers me is that many people equate being anti-occupation with anti-American.
Many reports do not touch on the
realities in Iraq, Riverbend says
I am not anti-American - I know many wonderful Americans and correspond and communicate with them regularly. I am, however, anti-occupation.
I don't wish for the "days of Saddam", if that's what you're asking. I am, however, completely against the presence of foreign troops in Iraq.
Why do you refer to the current Iraqi government as puppets?
Because almost all of them are allied with one foreign government or intelligence agency or another. None of them seems to have Iraq's best interests at heart. They are all too busy lining their pockets in preparation for their comfortable retirement from the Green Zone to outside of the country.
Where did you learn to speak and write in English?
I was raised abroad as a child and was fortunate enough to have parents who encouraged me to read continuously in English after we returned.
What types of books did you read?
I read any book in English I could get my hands on. I read the classics - books by Dickens, Jane Austen, William Thackery, George Orwell and others. I also read books by American authors like Faulkner. I read books translated to English from other languages - Russian and French literature. Anything I could find in English, I would read.
The Bronte sisters specifically changed my life – they opened me up to writing.
"I don't wish for the 'days of
Saddam'," Riverbend says (file)
So you always wanted to be a writer?
No - I didn't even know I could write until I began blogging.
Are foreign language books easy to find in Baghdad?
The classics are fairly easy to find if you know where to go... Newer books were very difficult to get, especially during the embargo. Sometimes we would ask people coming from abroad to just bring books - any books - because there never seemed to be enough.
Why do you maintain anonymity?
Because it keeps me secure. In the beginning, I decided to be anonymous because it gave me the freedom to discuss whatever and whomever I wanted without fear of retribution - this includes political parties, religious figures, common thugs masquerading as political and religious figures, etc.
I couldn't do this with the use of my name because I would be worried about detention or worse. People have been a lot less critical than I've been on my blog and they've gotten into a lot of trouble.
You have kept your blog alive for nearly three years. Do you ever envision it ending?
When Baghdad Burning was one of only six or seven Iraqi blogs, I would tell myself that the blog would remain alive as long as there was something to blog about.
"The sounds of shooting and explosions usually begin at dawn, at least that's when I first sense them, and they don’t really subside until well into the night"
Baghdad Burning, February 27
Now, there are dozens of Iraqi blogs from inside and outside of the country and where one blog ends, others will continue.
Blogging and journalism seem to be merging around the world. Are bloggers the new journalists?
Bloggers are not exactly journalists, which is a mistake many people make. They expect us to be dispassionate and unemotional about topics such as occupation and war, etc. That objective lack of emotion is impossible because a blog in itself stems from passion - the need to sit for hours at one's computer, slouched over the keyboard, trying to communicate ideas, thoughts, fears and frustrations to the world.
What future do you see for Iraq?
Possibly several more years of chaos. As long as there are foreign troops in the country, there's going to be violence and bloodshed. I do believe Iraq will rise once more - because Iraqis have a history of greatness.
