Studying Versioning in Stack Overflow

In Stack Overflow (SO), a post consists of multiple components: title, question, answers, question tags, and comments. Developers can create any of these components and make changes, which we call 'edits'. Edits are an important aspect of QA websites to ensure the quality and correctness of the texts. We performed multiple analyses on the revision history of 23 million SO posts from 2008 to 2023, and we gain a more comprehensive understanding of developers' content maintenance behaviors which lay the foundation for further research.
