I wrote a weekly newspaper column for more than five years. After that, I wrote a weekly column for Reuters, the financial wire service, for seven years. After a dozen years, writing something once a week – or more – was so second nature that when I stopped working to take care of my kids, I kept writing weekly columns. It’s just that for a time, my “weekly column” was the weekly email update for my oldest kids’ summer swim team. Then it was the weekly report for my son’s middle-school football team. Then it was a weekly newsletter for a charity group my daughter and I belonged to. It didn’t really matter what I was writing about, I was writing.

When I went back to work, I had to get acquainted with the technical aspects of blogging. But on the writing end of things I was good. Because really, I’d never stopped.

All of this is a round about way of saying, if you’re a writer, you need to write, and one of the best ways to practice is a blog. If you blog, it gets you into the habit of writing often. It’s like playing the piano. The more you practice, the faster you get better. The more you write, the faster you get better.

That’s reason No. 1 freelance writers should have a blog. Having a blog can also help you:

Create a Website – Sign up with a free blog hosting site like WordPress (what I use), TypePad or Blogger, and for nothing more than your email address, you get an online home for your resume, bio and clips as well as a blog.

Establish a beat - Whether it’s the 2008 presidential campaign, animal rescue or vegan cooking, blogging about a particular subject can help you stay on top of interesting trends and developments in a specific field, information that you can use for queries and assignments.

Practice different writing styles – If you normally writing in one style, you can use your blog to practice different styles or voices. If you normally write straight news stories for business or trade magazines, use your blog to practice writing opinion pieces, personal essays or comedy bits. If you’re comfortable writing in different styles and genres for yourself, it’s not much of a stretch to pitch those types of stories to potential clients.

Become an expert – If you blog on a specific topic long enough, you can develop an expertise that’s so attractive editors will come looking for you – or at least that’s the hope. You might also draw conference organizers looking for speakers and like-minded writers who want to network. Which leads to….

Make connections – Your blog can be a calling card to introduce yourself to writers, editors and other people in your field. Since I wrote about blogs for writers, a bunch of writers whose blogs I mentioned have asked to put me in their blogrolls and I’m doing likewise. Bingo, instant community.

Interact with readers – When you write for magazines or newspapers, you don’t always get the chance to interact directly with readers. Some publications still don’t run writers’ email addresses with stories and others run a generic address for all letters to the editors. On a blog there’s no barrier between you and your readers, so you can respond to whatever they have to say, which could lead to more things to write about.

Improve your skills – As publications move from paper to the Web, writers have to follow. You don’t need to know everything there is to know about coding HTML, but you should know a little. That goes for podcasts, social networks and other Web-based software too.

Get instant gratification - Send a story idea to a magazine editor and it might take weeks or months to hear back. Seeing a story in print can take even longer. On a blog, you get an idea, do some research, write it, hit the “Publish” button, and there it is, your thoughts for the world to see.

Make money – Although many writers use blogs purely for marketing and networking purposes, some have turned them into money-making ventures. They sell ad space through Google AdSense or sign up for the Amazon Associates program, or use the space to sell self-published books, e-books, webinars, podcasts and related services. You may find that you like blogging so much you want to look for freelance blogging gigs, which you can find on sites like ProBlogger and BloggerJobs.

Newspapers see the future, and it’s digital. The latest evidence: earlier this week the New York Times Co. and three other investors sank $29.5 million into Automattic, the company that makes WordPress blogging software runs the WordPress.com free blogging Website. (Disclaimer: I use WordPress.com to create and host this blog.)

According to a news report, the Times was the smallest of the four investors – the others were venture capital firms. But the deal solidifies the paper’s existing relationship with Automattic, which the Times uses to host about 50 blogs, as well as About.com, the Internet information service it acquired in 2005.

As the Times investments illustrate, newspapers’ embrace of digital media has moved beyond erecting Web sites and asking reporters to write blogs. Consider:

• E.W. Scripps, the Cincinnati media conglomerate, is so jazzed about the prospects of its TV and online ventures the company is set to spin them off into a separate public company later this year.
• Ruport Murdoch, new owner of the Wall Street Journal, told the World Economic Forum in Davos, Switzerland, on Thursday that he will keep subscriptions for the paper’s online version, though prices will be higher and some “commodity” financial information will be free.
• I’ve already written about how the Los Angeles Times’ Innovations (read Web site) editor, Russ Stanton, is being mentioned as a front runner for the now vacant editor-in-chief gig.

At the same time, newspapers’ economic prospects are looking dim. The latest on that front: the Orange County Register, my old stomping grounds and the place I got started as a tech reporter, is killing its stand-alone Business section and folding it into the News section in one of several cost-cutting measures. When it does, it’ll be the only major daily in the country without a separate Business section. Ouch.

What does it mean for freelancers? Bone up on your coding skills. Seriously, as newspapers go through this transition to digital, it’s more important than ever to keep up with the times, and the Times. Maintaining a blog is one way. Seeking out Web-based work is another. If you don’t believe me, this blog post from Publishing 2.0 called The Only Way for Journalists to Understand the Web is Use It says it a lot more eloquently than I can.

That leads me back to Automattic. The investment is great news for the two-year-old start up, whose major competition includes Blogger, which Google bought in 2003. Other blogging software makers don’t have such deep pockets, but there are a lot of them, including Six Apart, which makes Movable Type and TypePad, plus a host of smaller proprietary and open-source blogging software makers. Automattic said it will use the investment to beef up projects like Akismet, a blog comment spam blocker.
