To improve the CHI conference, would you share which talks you attended?

I’m having a great time at CHI (including my first time two-stepping today) but I strongly believe, as Jonathan Grudin asserted today, that we can make use of data to improve the conference.  I’ve already analyzed historical data that demonstrates that we can substantially reduce reviewer workload.  We’ve also created a way you can use [...]

For CHI 2012: Discussion Forums in the Document Margins

Would you like some feedback on your CHI paper?  We’ve set up a site to let people read and comment on it.
On Wednesday at CHI, we’ll be presenting our paper on nb, a discussion forum situated in the margins of documents being discussed.  Its original intended usage was for discussion of classroom lecture notes, but [...]

Forums in the Document Margins for Classes and Reading Groups

Eating our own Crowdfood

Recently the CHI workshop on Crowdsourcing and Human Computation got some press courtesy of Jim Giles and New Scientist. Near the end of the workshop, the working group on Future Directions and Community had some interesting suggestions that I’ll echo here.

Who's answering your questions?

Over the course of the last year or so, I’ve been looking at the way people ask and answer questions on Facebook. Much of this work happened with the phenomenal and (haystack alum!) at .

Is it better to be messy or neat? An etiology of messiness

When someone describes a person as a “messy” or “tidy”, we can instantly guess something about their appearance, their personality, and the way they organize their physical and digital artifacts – around the house, office, or on their computer(s). There is little disagreement around these definitions, and many stereotypes (both positive and negative) are [...]

CSCW, the Attention Economy, and Efficient Information Markets

At last week’s CSCW conference, two papers were connected by a theme I find quite interesting—the question of establishing efficient information “markets” that direct the production and consumption of information to where it has the greatest utility.
“”, by Geyer and Dugan, described a nice system aimed at soliciting and directing the energy of bloggers [...]

CSCW 2010 examines Wikipedia

I just got back from my first attendance at (half of) CSCW.  It was an enjoyable and enlightening conference.  Overall, my favorite session was the first one I attended—four quite interesting papers studying the use of Wikipedia were presented.
The first, Socialization Tactics in Wikipedia and their Effects, by Choi, Alexander, Kraut and Levine, studied how [...]
