Two hours is a long time to sit in front of your computer watching video. Fortunately, you can download an MP3 here.

We will have an all-star cast: David Dahl, the Boston Globe’s regional editor, who’s in charge of the paper’s regional editions and the hyperlocal Your Town sites; Callie Crossley, host of “The Callie Crossley Show” on WGBH Radio (89.7 FM) and a fellow panelist on “Beat the Press” (WGBH-TV, Channel 2); and Adam Gaffin, the co-founder, editor and publisher of Universal Hub, Greater Boston’s one essential hyperlocal news site.

The free event will take place from 5o to 7 p.m. in the MIT Media Lab’s Bartos Theater, at 20 Ames St. in Cambridge. It’s being held at the same time that the Online News Association’s annual conference gets under way in Boston, and we’re hoping a few attendees decide to wander over as well.

Go ahead and click — unlike the model that prevails elsewhere online, Media Nation does not charge extra per click. Which means that even I can click through without costing Chan Miller any additional money.

I am deeply appreciative of Chan Miller’s sponsorship of Media Nation, which came about when partner Ken Gornstein responded to this post. I’m hoping to unveil another local sponsor in the near future.

So what happened to Google ads? They’re now in the upper right, below the header, where the Flyerboard used to be. The Flyerboard, administered by the Boston Blogs advertising network, had fallen on hard times. I’ll bring it back if that changes.

Handling the technical details is Adam Gaffin, editor and publisher of Universal Hub. There is no better friend to the Boston blogging community than Adam.

I said a blogger should have been included in the discussions. And I even had a suggestion: Adam Gaffin of Universal Hub, who’s probably the most respected independent blogger in Greater Boston.

As it turns out, Gaffin was, in fact, a part of those discussions, according to Robert Ambrogi, a media lawyer who is executive director of the Massachusetts Newspaper Publishers Association.

Obviously I wish I’d known that before I opened my mouth.

This week, I finally figured out how to undo the damage. The indefatigable Adam Gaffin of Universal Hub — who also supplies local bloggers with the “Flyerboard” ad that appears in the right-hand column — helped me with the coding.

We’ll see what happens.

Let me repeat: The most interesting local online journalism is taking place at the grassroots. And no one in Greater Boston does a better job of aggregating it than Adam Gaffin of Universal Hub. If you didn’t know that already, well, now you do.

(Disclosure: Media Nation is part of Gaffin’s Boston Blogs advertising network.)

Earlier item.

The blabbing continues. From 3:45 to 5 p.m., Adam Gaffin of Universal Hub and I will lead a workshop on “Writing for the Web.”

Finally, on Saturday from 1:45 to 3:15 p.m., I’ll be taking part in a panel discussion on social media that’s part of the ACLU of Massachusetts “Secrecy, Surveillance and Sunlight” conference at UMass Boston. I’ll be joined by Northeastern University Law School professor Hope Lewis, ACLUM online communications coordinator Danielle Riendeau and ACLUM communications director Christopher Ott.

Now, to get back to those slides (and sorry for the funny line breaks; there’s something about SlideShare that I’m obviously missing). There are a number of examples I’ll be talking about that are worth taking a deeper look at. So I thought I’d post some links here.

Amy Derjue (from Twitter)

Adam Gaffin of Universal Hub has some big-time fun with the Boston Herald’s story on city employees who use Facebook and Twitter during work hours. Gaffin reproduces a photo of the Herald reporters who wrote the story, Jessica Heslam and Dave Wedge, from — yes — Heslam’s Facebook account.

“What are they using them for?” asks Gaffin. “What are they hiding? Ooh, insinuation is fun!”

Kidding aside, you have to admit that there’s an appearance problem with the way some city employees are using social media. Heslam and Wedge focus on Amy Derjue, a former Boston Magazine blogger who was hired earlier this year to serve as City Council president Mike Ross’ $39,000-a-year spokeswoman.

Derjue is something of a young-woman-about-town, and I follow her on both Facebook and Twitter. (If you page through her 340 Facebook friends, you’ll see a wide array of local media and political folks, including Gaffin, me — and Wedge.) Some of her posts make me cringe, and Heslam and Wedge dutifully provide some cringe-worthy examples. But I’ve never heard anyone suggest she wasn’t smart, hard-working and energetic. For what it’s worth, she has complained to me on behalf of her boss, which suggests dedication to her job.

More to the point, most of us — and you can be sure Derjue falls into this category — are never fully off work. If we’re expected to tend to business when we’re off-duty, then we have to be allowed some fun during the formal workday as well. And, as Gaffin writes, “Why, it takes sheer seconds to post something to Facebook or Twitter.”

An aside that may help illustrate my point. Yesterday John Robinson, editor of the News & Record in Greensboro, N.C., tweeted that he was being yelled at by a “legislator who resigned in disgrace.” When I responded at how impressed I was with his multi-tasking, he replied, “Yes, tweeting while yelling. What else am I supposed to do? Listen?” This was not a private conversation — it was seen by all 1,196 of Robinson’s followers and all 2,019 of mine. Welcome to 2009.

Ross tells the Herald that he hired Derjue in part for her social-networking expertise. And, indeed, Ross has a pretty lively Twitter feed and Facebook account. For Derjue to post to her personal sites while working on her boss’ would, as Gaffin says, take “sheer seconds.” You can question her judgment, but her social-media activities are not evidence of dereliction.

Derjue seems to have partly disabled her Facebook account (I could be wrong; Facebook mystifies and annoys me), and she hasn’t posted to Twitter since last night. No doubt she’s licking her wounds at the moment. I’m interested to see how she’ll respond.
