"Digital fluency" should mean designing, creating, and remixing, not just browsing, chatting, interacting.
We present two studies of online ephemerality and anonymity based on the popular discussion board /b/ at 4chan.org: a website with over 7 million users that plays an influential role in Internet culture. Although researchers practitioners often assume user identity data permanence are central tools design communities, we explore how succeeds despite being almost entirely anonymous extremely ephemeral. begin by describing performing content analysis suggests community is dominated playful...
Despite the proliferation of explainable AI (XAI) methods, little is understood about end-users’ explainability needs and behaviors around XAI explanations. To address this gap contribute to understanding how can support human-AI interaction, we conducted a mixed-methods study with 20 end-users real-world application, Merlin bird identification app, inquired their needs, uses, perceptions. We found that participants desire practically useful information improve collaboration AI, more so than...

Social and political bots have a small but strategic role in Venezuelan conversations. These automated scripts generate content through social media platforms then interact with people. In this preliminary study on the use of Venezuela, we analyze tweeting, following retweeting patterns for accounts prominent politicians bots. We find that very proportion all traffic about life Venezuela. Bots are used to retweet from effect is subtle less than 10 percent retweets come bot-related platforms....
Data videos, or short data-driven motion graphics, are an increasingly popular medium for storytelling. However, creating data videos is difficult as it involves pulling together a unique combination of skills. We introduce DataClips, authoring tool aimed at lowering the barriers to crafting videos. DataClips allows non-experts assemble "clips" form longer sequences. constructed library clips by analyzing composition over 70 produced reputable sources such The New York Times and Guardian....
Digital avatars are an important part of identity representation, but there is little work on understanding how to represent disability. We interviewed 18 people with disabilities and related identities about their experiences preferences in representing avatars. Participants generally preferred disability if the context felt safe platforms supported expression, as it was for feeling authentically represented. They also utilized strategic ways: a means signal disclose current abilities,...
Although we may complain about meetings, they are an essential part of information worker's work life. Consequently, busy people spend a significant amount time scheduling meetings. We present Calendar.help, system that provides fast, efficient through structured workflows. Users interact with the via email, delegating their needs to as if it were human personal assistant. Common scenarios broken down using well-defined workflows and completed series microtasks automated when possible...
To help activists call new volunteers to action, we present Botivist: a platform that uses Twitter bots find potential and request contributions. By leveraging different accounts, Botivist employs strategies encourage participation. We explore how people respond calling them action using test case about corruption in Latin America. Our results show the majority of (>80%) who responded Botivist's calls contributed relevant proposals address assigned social problem. Different produced...
Theorists and advocates of "remixing" have suggested that appropriation can act as a pathway for learning. We test this theory quantitatively using data from more than 2.4 million multimedia programming projects shared by 1 users in the Scratch online community. First, we show who remix often larger repertoires commands even after controlling numbers amount code shared. Second, exposure to computational thinking concepts through remixing is associated with increased likelihood those...
Effective task management is essential to successful team collaboration. While the past decade has seen considerable innovation in systems that track and manage group tasks, these innovations have typically been outside of principal communication channels: email, instant messenger, chat. Teams formulate, discuss, refine, assign, progress their collaborative tasks over electronic channels, yet they must leave channels update task-tracking tools, creating a source friction inefficiency. To...
We present a qualitative analysis of interviews with participants in the NoSleep community within Reddit where millions fans and writers horror fiction congregate. explore how handled massive, sudden, sustained increase new members. Although existing theory stories like Usenet's infamous "Eternal September" suggest that large influxes newcomers can hurt online communities, our survived without major incident. propose three features allowed it to manage rapid influx gracefully: (1) an active...
With the growing ubiquity of wearable devices, sensed physiological responses provide new means to connect with others. While recent research demonstrates expressive potential for biosignals, value sharing these personal data remains unclear. To understand their role in communication, we created Significant Otter, an Apple Watch/iPhone app that enables romantic partners share and respond each other's biosignals form animated otter avatars. In a one-month study 20 couples, participants used...
There has been much recent interest in the development of tools to foster remote collaboration and shared creative work. An open question is: what are guidelines for this process? What key socio-technical preconditions required a geographically distributed group collaborate effectively on work, they different from conditions decade or two ago? In an attempt answer these questions, we conducted empirical studies seemingly very online communities, both requiring effective work: international...
Social media platforms have emerged as prominent information sharing ecosystems in the context of a variety recent crises, ranging from mass emergencies, to wars and political conflicts. We study affective responses social how they might indicate desensitization violence experienced communities embroiled an armed conflict. Specifically, we examine three established affect measures: negative affect, activation, dominance observed on Twitter relation number statistics protracted four major...
In this paper, we explore the role that attribution plays in shaping user reactions to content reuse, or remixing, a large user-generated community. We present two studies using data from Scratch online community – social media platform where hundreds of thousands young people share and remix animations video games. First, quantitative analysis examines ef- fects technological design intervention introducing au- tomated remixes on users’ being remixed. compare parallel examination “manual”...
This paper examines the sociotechnical infrastructure of an "indie" food delivery platform. The platform, Nosh, provides alternative to mainstream services, such as Doordash and Uber Eats, in several communities Western United States. We interviewed 28 stakeholders including restauranteurs, couriers, consumers, platform administrators. Drawing on literature, we learned that is a patchwork disparate technical systems held together by human intervention. Participants join this because they...
Trust is an important factor in people's interactions with AI systems. However, there a lack of empirical studies examining how real end-users trust or distrust the system they interact with. Most research investigates one aspect lab settings hypothetical end-users. In this paper, we provide holistic and nuanced understanding through qualitative case study real-world computer vision application. We report findings from interviews 20 popular, AI-based bird identification app where inquired...
