New York Times Executive Editor Bill Keller penned a letter to the New York Review of Books, in reply to a Michael Massing article on the Internet and the news business. After defending his paper's Internet presence, Keller found a blog he actually likes, praising left-wing blogger-journalist Josh Marshall, who operates the Talking Points Memo blog. 

I've long been an admirer of the best practitioners of Web journalism, including many of the familiar faces Massing introduces to the Review's readers. My respect for Josh Marshall, to cite everyone's favorite example of a serious journalism venture born online, is all the greater because his success remains, so far, a rarity and a struggle.

At least one media outlet is bucking the field's bleak economic outlook: The left-wing blog Talking Points Memo. On Monday, Noam Cohen reported in the New York Times that TPM has received funding from outside investors that will result in a doubling of staff, and may include some veteran mainstream journalists.

The political news Web site Talking Points Memo this weekend completed a round of investment, of $500,000 to $1 million. The move is intended to increase the number of employees, to roughly 20, from the current 11, in the next 10 months.

The financing is the first part of a three-year plan to increase the site's staff to 60 employees, Joshua Micah Marshall, the site's founder, said in an interview at his offices on West 20th Street in New York.

Marshall, who in TPM's early days (the blog was launched during the Florida recount fight of Election 2000) was less reflexively anti-Republican than today, has beefed up the once-humble blog to include TPM café, a discussion site, and TPM Muckraker, an investigative site almost exclusively devoted to conservative scandal-mongering.

Although the established media often rails against bloggers, Marshall is an exception. As Cohen reported back in February 2008, Marshall won the media's George Polk Award for legal reporting for his work on the Bush administration firing eight U.S. attorneys under what TPM and other liberals claimed were politically motivated circumstances -- a perfectly legal effort that was nonetheless considered scandalous by mainstream media.

UPDATE at end of post: Dowd's employing the famous "I heard it from a friend" defense.

On a regular basis, NewsBusters has warned readers of the infiltration into traditional media outlets content written by left-wing bloggers.

On Sunday, New York Times columnist Maureen Dowd was accused of plagiarizing a piece posted a few days prior by Josh Marshall of the liberal website Talking Points Memo.

Dowd has now admitted her mistake.

As Marshall wrote Thursday (h/t Hot Air):

So much for any pretense of balance. Looks like David Shuster has taken a page from Keith Olbermann's playbook: play exclusively to your crowd; exclude any alternative voices.

Announcing this evening a new regular feature focusing on the blogosphere on his 1600 Pennsylvania Avenue show, Shuster made it clear that conservatives need not apply.

DAVID SHUSTER: Every day at this time, we're going to bring you a key issue in the progressive blogosphere.
