Exploring Complexity: We Need to Talk About Scaling (Melanie Mitchell)
"In my next several blog posts I want to talk about scaling, especially about the very recent controversies surrounding claims of power-law scaling of particular phenomena [...] All this is going to require some forays into the wild and unruly land of statistics and data analysis. My goal in the next series of posts is to make sense of the following quite important papers in complex systems, which, taken together, form a kind of mini-course on scaling. Understanding ideas from these papers is essential in one’s education as a complex-systems scientist or informed “consumer” of this field."

C is a poster child for why it’s essential to keep those people who know a thing can’t be done from bothering the people who are doing it.

The Fans Are All Right (Pinboard Blog)
"I learned a lot about fandom couple of years ago in conversations with my friend Britta, who was working at the time as community manager for Delicious. She taught me that fans were among the heaviest users of the bookmarking site, and had constructed an edifice of incredibly elaborate tagging conventions, plugins, and scripts to organize their output along a bewildering number of dimensions. If you wanted to read a 3000 word fic where Picard forces Gandalf into sexual bondage, and it seems unconsensual but secretly both want it, and it's R-explicit but not NC-17 explicit, all you had to do was search along the appropriate combination of tags (and if you couldn't find it, someone would probably write it for you). By 2008 a whole suite of theoretical ideas about folksonomy, crowdsourcing, faceted infomation retrieval, collaborative editing and emergent ontology had been implemented by a bunch of friendly people so that they could read about Kirk drilling Spock." --- See also the very last link.

Collective Wisdom — Crooked Timber
"More broadly, a simple dictum such as ‘listen to the experts’ isn’t going to work, precisely because our most powerful methods of generating new knowledge (viz. the sciences) are not so much based on listening to individual experts, as on including these experts (and many others) in broader social systems which expose them continually to the ideas of others and vice-versa. Designing (or – perhaps better- nurturing) such systems is hard to think about and hard to do – but it has to be the way forward."

Schumpeter: Rules for fools | The Economist
"…Florida’s legislature recently debated a bill to remove licensing requirements from 20 occupations, including hair-braiding, interior design and teaching ballroom-dancing. For a while it looked as if the bill would sail through: Florida has been a centre of tea-party agitation and both chambers have Republican majorities. But the people who care most about this issue—the cartels of incumbents—lobbied the loudest. One predicted that unlicensed designers would use fabrics that might spread disease and cause 88,000 deaths a year. Another suggested, even more alarmingly, that clashing colour schemes might adversely affect “salivation”. In the early hours of May 7th the bill was defeated. If Republican majorities cannot pluck up the courage to challenge a cartel of interior designers when Florida’s unemployment rate is more than 10%, what hope has America? The Licence Raj may be here to stay."
