My eye was caught today by a
recent paper (2017) release by Cornell on the participation of people in online Q&A communities for creating useful,
crowdsourced information.
From the paper's abstract:
The success of Stack Overflow and other community-based question-and-answer (Q&A) sites depends mainly on the will of their members to answer others’ questions. In fact, when formulating requests on Q&A sites, we are not simply seeking for information. Instead, we are also asking for other people's help and feedback. Understanding the dynamics of the participation in Q&A communities is essential to improve the value of crowdsourced knowledge.

The use of crowdsourcing is also what TechExams.Net has depended on to be a leading source of IT certification information and advice since 2002. I completely agree with the paper's assessment that the presentation quality of both question and and answers is "among the driving factors of the success of requests in Q&A sites." As a contributor myself to TE since 2003, I am very gratified that TE has attracted the highest quality of continuing contributions from the people of the online IT certification community.
You might think this paper to be
tl;dr, but if you spend a lot of time in online discussion forums then you should find its findings interesting.
