Researchers @citp@micro.blogs.princeton.edu and @hci@micro.blogs.princeton.edu are studying what happens when social media users are able to take control of what they see in their feeds, rather than relying on an algorithm.
While users felt freed from the algorithm, they found there was also a trade-off: It can be more work when you have to be intentional about curating a feed.
The work, by Omar El Malki, Marianne Aubin Le Quéré, @manoel@hci.social and @andresmh@hci.social, will be presented this week at the ACM CHI conference.
Maryam Hedayati, an expert in human-computer interaction, has joined the computer science department as a member of the teaching faculty.
Inspired by her undergraduate professors Carleton College, Hedayati is excited to introduce Princeton students to computer science. In an intro class, she said, students are learning to think in a whole new way. "I really enjoy helping them through that.”
Until now, pricing structure on rideshare apps has been opaque. 🚗
To help fix this, The Workers' Algorithm Observatory, including @andresmh@hci.social and @varunrao@hci.social created the FairFare app to crowdsource payment info from drivers.
Now, thanks in part to the data collected by FairFare, Colorado has passed a law mandating rideshare payment transparency.
