What Twitter is good for:

Self-assessment

Found a new power law distribution today. It’s hopelessly geeky that it excites me so much but I’m learning to accept that about myself. — @KentBeck

Felt out of place on a flight w/ 80% consultants. Am I a free spirit or just a child with my farm-animal decal laptop? — @verbicidal

Tabs in JavaScript make me sad. — @tswicegood

I’m personally comfortable with the armadillo races, but appalled by one of the other entertainment options: a gunfight (ugh!) #cscw2013 — @asbruckman

I’m having a day where I actually feel like I know what I’m doing. — @mtnygard

Estimated I’ve spent ~500 hours making cappuccino. I should be an expert by age 165. — @jbrains

Sharing the Secret to Your Productivity

Drinking a Howard Street IPA by ThirstyBear Brewing Company. — @pleia2

It’s amazing how many questions can be answered with Laphroaig. — @scottdavis99

Today’s motto: Powered by Girl Scout cookies. #NICAR13 — @MacDiva

If you put a million monkeys at a million keyboards, one will eventually write a Java program. The rest of them will write Perl programs. — @barse

Today I’m going to do all of the things. — @SaraJChipps

Sharing Your Insights

Forget 3D printing. MIT has already moved on to 4D. 4D refers to 3D items that transform themselves over time. — @sara6633

In customer acquisition, your churn rate is your most important metric. Trust me. — @HackerChick

The startup (revenue) hockey stick is really just a mullet: business in the front, party in the back. — @HackerChick

To people at lectures/conferences everywhere: please turn off the sound on your phone while you take photos. Fake shutter ? real shutter. — @natalierachel

I wear a bow tie now. Bow ties are cool. — @neilhimself

Just Sharing

Moved the dog’s water dish to the bathroom in hopes of keeping him from drinking from the toilet. Now he has toilet water for dessert. Ugh. — @storming

Mtn View Voice “Toxic vapors found in #Google offices” (Whisman area, new offices). So much new development there. :( — @LatinasInC

I have been told that I fail at RSS, and need to declare RSS bankruptcy. (I have 14k items unread in NetNewsWire.) — @snipeyhead

I’m gonna start looking up and to the right all the time so when I get Google Glass you won’t be able to tell if I’m ignoring you. — @seldo

The 1px problems will be the death of me. — @zahnster

Second-Guessing Marissa Mayer

Technology allows millions of people to work from home. Yahoo, a big tech firm, is trying to stop them. — @TheEconomist

FWIW, I never doubted Yahoo’s new policy about working in office. Companies can gather lots of dead wood. Let’s get to know our colleagues. — @davewiner

What JC Penney has in common with Yahoo is that people tend to goof off when they fall into despair. — @dhh

Next time we second guess a decision from Marissa Mayer we should remember she’s data driven and doesn’t make decisions like this wildly. — @kellabyte

Who Are Those Guys?

First, they’re not all guys. Second, we have to confess that we cleaned up their punctuation and stuff a little. OK, who we followed this month: Kent Beck, Natalie Be'er, Amy Bruckman, Sara Chipps, Sara Czyzewicz, Scott Davis, Andrew W. Deane, The Economist, Abby Fichtner, Neil Gaiman, DHH, Elizabeth Krumbach, Latinas in Computing, Michael Nygard, Terri O, Thomas Powell, J. B. Rainsberger, Jade Rauenzahn, Lars Sjögreen, snipe ?, Kelly Sommers, Amy Stephen, Stormy, Travis Swicegood, verbicidal, Laurie Voss, Dave Winer, and Chrys Wu.
