No place for negative emotions? The effects of message valence, communication channel, and social distance on users’ willingness to respond to SNS status updates
作者：
Highlights：
• The availability of public social support on SNSs is limited by communicative norms.
• We extend the concept of a “positivity bias” to responses to SNS status updates.
• Negative status updates impede users’ willingness to respond with a public comment.
• Response willingness is mediated by message appropriateness and support urgency.
• Only close friends are willing to provide support via private messages.
