Anil Dash has a great explication of the issues surrounding what it means for something to be “public” and how we talk about “public” and how we defend or rely on that status, defining it and redefining it.
He calls attention to an increasing reliance on binary definitions: friends/global, public/private, when these are obviously over-simplified. He writes:
…there are two communities keenly interested in reducing the complexity of publicness:
The media industry benefits from things that are in a gray area being treated as “public”, because this makes it (at best) fair game for discussion or (at worst) raw materials to feed the insatiable need for new content.
The technology industry benefits from treating “public” as a binary state because handling more complex forms of privacy can be more expensive to accommodate in software, and because tech companies increasingly rely on the same advertising model which supports media, where public information is more valuable because it can be monetized.
We’ve spent so many years being indoctrinated in this new, false definition of what is public that most people will still not concede that there is any complexity to the issue.
… and proud of it!
The New York Times recently ran an article on how 50-80% of data science is “janitor work” like data cleaning and wrangling. This, along with data collection, is of course my favorite part of doing my job, so I liked the article. Check it out!
Yet far too much handcrafted work — what data scientists call “data wrangling,” “data munging” and “data janitor work” — is still required. Data scientists, according to interviews and expert estimates, spend from 50 percent to 80 percent of their time mired in this more mundane labor of collecting and preparing unruly digital data, before it can be explored for useful nuggets.
“Data wrangling is a huge — and surprisingly so — part of the job,” said Monica Rogati, vice president for data science at Jawbone, whose sensor-filled wristband and software track activity, sleep and food consumption, and suggest dietary and health tips based on the numbers. “It’s something that is not appreciated by data civilians. At times, it feels like everything we do.”
I’ll be speaking at All Things Open this year in Raleigh. My talk is titled “We’re Watching You: How and Why Researchers Study Open Source And What We’ve Found So Far”. Spoiler alert: I conclude open source developers are jerks, get thrown out of conference. Just kidding. Sort of.

My students in Data Mining (ISC 420) know about doing this kind of text analysis! Last semester we analyzed lots of lyrics and did sentiment mining on them too.
