I asked "What exactly is githubissues.com?" and Quick answer replied the folowing:
Based on the information provided, githubissues.com does not appear to be a real website. The information discusses GitHub Issues, which is a feature provided by the GitHub platform, not a standalone website.
The key points are:
GitHub Issues is a feature within the GitHub platform used for reporting bugs, requesting features, hosting discussions, and processing support requests. 12
GitHub Issues allows users to create and track work, receive feedback, collaborate on ideas, and communicate efficiently with others. 3
GitHub Issues is not a separate website, but rather a part of the overall GitHub platform for software development and collaboration. 4
So in summary, githubissues.com is not an actual website - the information is referring to the GitHub Issues feature within the GitHub platform, not a standalone website.
However, the website do exist: https://githubissues.com/
Quick answer should found the related info of the website and gave a summary of it.
