I'm looking for empirical papers which investigate if a user can benefit from Q&A sites like Stack Overflow. I welcome any papers related to this topic, e.g:
- an experiment, investigating if a specific task can be executed faster,
- an analysis, investigating if a user understands the solutions on Q&A sites or if he just does copy&paste without thinking about it,
- a comparative analysis of the code quality of users with access to Q&A sites in contrast to users without internet access (but just offline documentation of APIs).
