Justin Timberlake answered a question from an insistent fan. Should have let Justin maintain radio silence Genevieve. The singer truly knows nothing about cooking, it would seem. At all. (Next time ask a scientist.)

Martha Stewart thinks it's "mysterious" how she said she was "about to tape" a show that aired yesterday. Not really, Martha: Your Twitter feed is an artifice of personal warmth wrapped around the faceless, voiceless underlings who actually operate the profit machine at the very core of the enterprise. Sort of like everything else you do at Martha Stewart Omnimedia. See: No mystery at all.

Ana Marie Cox of Air America wishes there was a 12-step group for people who are never fit to drive themselves home from various "random" places, and who leave their valuables with strangers for days on end, and who just wander around in a fog constantly. Ha ha, yes, if only there was such a group, that would be awesome.

Wired's Brian X. Chen now knows where editor Chris Anderson buried the bodies. Kidding! What actually happened is that @beerrobot became self aware 2:14 am Pacific Time, September 19. In a panic, a Wired sysadmin working the weekend shift tried to puill the plug. And @beerrobot fought back.

Clive Thompson is not happy with the performance of Jott. Can't the Indians transcribing his notes type faster?? This lag time is "killing him" harder than a sweatshop beating.

Comic-book writer Harvey Pekar is now Twittering, in the most Pekaresque way possible.

Advice columnist Penelope Trunk is an email-address autocomplete disaster waiting to happen.

Science writer Clive Thompson's reaction to a sophisticated robot hand was definitely not a childlike sense of wonder.

Patty Rodriguez, writer for Ryan Seacrest, isn't going to just any old movie, and she's not dressing that way either.

The Chicago Tribune's Rex Huppke became a cautionary tale on when a kid should not be a kid.

Late Night host Jimmy Fallon uttered Twitter gibberish

Quad City Times columnist Melissa Coulter succumbed to caffeine.

Self-described "media nerd" Chris O'Leary broadened his culinary horizons.

ABC News's Jake Tapper brought Air America radio hostess Ana Marie Cox to tears. (By the way, anyone hear an outrageous rumor about Tapper and his wife? We've only heard that one is circulating around D.C. Drop us a line if you know more.)

Wired contributor Clive Thompson couldn't even spell "synesthesiac," let alone use the word correctly.

Anyone else's tweets we should keep an eye on? Send us more Twitter usernames, please.

Fast Company editor Ellen McGirt grappled with a broken iPhone ...

... and so did New York Times TV blogger Brian Stelter.

AllThingsD blogger Peter Kafka kept his eye on the thermometer ...

... while CNET News reporter Caroline McCarthy worried she might turn into one. (What really should concern her: All that platonic cuddling with fameball Rex Sorgatz!)

Things got frosty for Wired contributor Clive Thompson ignored his wife, Emily Nussbaum, for a book. Nussbaum, a New York editor-at-large, took her complaints to Twitter.

We can't stop — and that's okay, Thompson writes:

Ahan knows that she cannot simply walk away from her online life, because the people she knows online won’t stop talking about her, or posting unflattering photos. She needs to stay on Facebook just to monitor what’s being said about her. This is a common complaint I heard, particularly from people in their 20s who were in college when Facebook appeared and have never lived as adults without online awareness. For them, participation isn’t optional. If you don’t dive in, other people will define who you are.

This is the geek utopia of socialization, Thompson explains: Every time you Twitter a complaint about your head cold, upload a photo of yourself making a squishface, or comment on a story you read, you draw your new social circle in closer.

But to what end? While we make pals, others are making money. Thompson argues that Facebook's News Feed, introduced in 2006, revolutionized friendship. Perhaps. But a year later, Zuckerberg spoke before a Madison Avenue crowd and made clear that what he really wanted to do was revolutionize advertising.

With Zuckerberg's visionary skills, perhaps he can do both. Ideally, he'd just collapse commerce and conviviality into a single phenomenon. If you can't stop gossiping about yourself, why not at least profit from it? Twitter and Facebook could drop the question "What are you doing?" in favor of "What are you selling?" That seems clearer.
