Lowering technology barriers has enabled more people to comment, more often. What effect has this had? Twitter and Weibo’s, by virtue of limiting the volume of text to be shared, has enabled more people to share more. It’s given rise to link-shortening and exported more SMS language and short-form communication into the mainstream Internet. There is a tendency amongst some to believe that what you’re reading in the comments is a representation of what people think. There are good models, found in marketing science research, that suggests that people experience products, then consider whether or not they’ll post something, and then moderate their opinions based on the audience. This two-step process is fairly important, especially when it’s applied to professional[…]

Short, free-form commenting technologies has enabled more people to say more things. Many technologists prefer users respond by hitting single buttons. Liking, wanting, upvoting, downvoting, thumbs up, thumbs down, share, +1, retweeting, favouriting and so on. Facebook is entirely focused on the affirmative actions. Reddit enables both actions. These are very easy to understand, and have their intended effects. Facebook wants you to share everything. Reddit wants the best content to aggregate to the top. Commenting requires a bit more effort, in that the user usually uses keyboard to generate a comment, hitting multiple keys, and sometimes creating words or even expressing a well formed thought. And so, it must follow, there’s an attention economy around commenting. Herp Derp is[…]
Heading into an analytics interview? There are a few things you should know. Pay attention to the description A few leading hiring managers have been listing specific items outright. For instance, we used to list “Will have an opinion about Peterson’s line on cookies” right in the description. We will ask you what your opinion is on Peterson’s opinion. If you don’t have one, we assume that you will do something prior to the interview to become informed, and, come with an opinion. Different hiring managers implant different preparation questions. Pay attention and prepare. If you’re heading into a department with a good reputation, it’s because they’re all prepared. And, since like people tend to clump together, we’re looking for[…]
Twitter shut off it’s API to LinkedIn, and released a post about delivering a consistent twitter experience. I’ve seen interpretations of the Twitter post ranging from ‘don’t mimic twitter’s functionality and you’ll be alright’ to ‘Twitter is killing its own ecosystem‘. Are you entitled to your Twitter entitlement? Why Twitter Has An API in the first place Offering an API is a strategic choice. They involve tradeoffs. An API costs Twitter: Money to serve, develop, and maintain Risk, from consumers and competitors alike What Twitter gets in return: Scale, in the form of features that are not, will not, or cannot be built by Twitter itself, that are built by other companies Innovation, in the form of observing the ecosystem[…]

Boxplots are a good way to examine the distribution of data. They allow you to see outliers and understand how it skews. The image below comes from the the US Labor Department 2011 Time Use Survey. The X-axis represents days of the week, Sunday = 1 and Saturday = 7. Along the Y-axis is t010101, the variable for ‘time sleeping’, and it is expressed in the form of minutes. This is what I see when I first crack open some data. It’s raw. You see a box and you see a dark line inside that box. The dark line is the MEDIAN, and the box contains half of all the observations in the sample. the dots represent individuals at the[…]
Mike Miller (@mlmilleratmit) wrote a piece entitled “Why the days are numbered for Hadoop as we know it.” The key paragraph is: “In summary, Hadoop is an incredible tool for large-scale data processing on clusters of commodity hardware. But if you’re trying to process dynamic data sets, ad-hoc analytics or graph data structures, Google’s own actions clearly demonstrate better alternatives to the MapReduce paradigm. Percolator, Dremel and Pregel make an impressive trio and comprise the new canon of big data. I would be shocked if they don’t have a similar impact on IT as Google’s original big three of GFS, GMR, and BigTable have had.” To simplify, in my words: The software package known as Hadoop is incredible for processing[…]
This is the final post in a series on how Americans live, based off the The US Labor Department 2011 Time Use Survey. In sum, Americans work hard. Those with household children under 6 spend on average: 2.85 hours a day doing housework (Women: 3.16) 2.33 hours a day caring for children (Women: 2.59) 30 minutes a day on education And that excludes the hours they spend in the paid workforce! You can’t say they play hard from the ATUS. If children or the elderly aren’t around to be looked after, the leisure time gets dumped into the Television sink – 2.57 weekday hours, 3.19 weekend hours. General (unattributable) game playing time is highest amongst youth – 1.03 weekday hours[…]
This is part 4 in a series on How Americans Live. The US Labor Department released the 2011 Time Use Survey on June 22. So far, we’ve seen how the American Time Use Survey (ATUS) is designed, why the hours worked measure appears to be low, and, why the computer use measure of 7 minutes is a product of coding design. On Simultaneous Activities ATUS focuses on quantifying primary activities only. And yet, it is the rise of the simultaneous activity that explains a lot about how Americans live. On average, an American spends 1.7 minutes a day listening to music (not radio), as a primary activity. That keyword – primary – is really important. On average, an American spends[…]
This is part 3 in a series on How Americans Live. The US Labor Department released the 2011 Time Use Survey on June 22. A few facts should raise questions: In 2011, each day, at the highest aggregated level, on average, an American spends: 2.75 hours watching TV 43 minutes buying goods and services 18 minutes exercising, playing sports, and recreating 10 minutes on telephone calls, mail, and email 7 minutes on leisure computer use (excluding games) 2.75 hours watching TV, 7 minutes computer use That 2.75 hour watching TV figure ought to stick out like a craw for many analysts, because, by some estimates, 19.25 hours a week is a really low figure. The same goes for 7 minutes[…]
