I was on a support group once before where most people showed their face pics. This support group was for cigarette smokers, drinkers, crystal meth, cocaine, heroin, marijuana, sex, gambling and other very heavy addictions.
I don't see much of that here.
Was just wondering what the reason was. Not here to judge anyone, it was merely an observation.
Studies have shown that people are more likely to engage with people that they can "see"
I include a paragraph from researchgate.net talking more about how faces engage us.
Photos are becoming prominent means of communication online. Despite photos' pervasive presence in social media and online world, we know little about how people interact and engage with their content. Understanding how photo content might signify engagement, can impact both science and design, influencing production and distribution. One common type of photo content that is shared on social media, is the photos of people. From studies of offline behavior, we know that human faces are powerful channels of non-verbal communication. In this paper, we study this behavioral phenomena online. We ask how presence of a face, it's age and gender might impact social engagement on the photo. We use a corpus of 1 million Instagram images and organize our study around two social engagement feedback factors, likes and comments. Our results show that photos with faces are 38% more likely to receive likes and 32% more likely to receive comments, even after controlling for social network reach and activity. We find, however, that the number of faces, their age and gender do not have an effect. This work presents the first results on how photos with human faces relate to engagement on large scale image sharing communities. In addition to contributing to the research around online user behavior, our findings offer a new line of future work using visual analysis.
