There are many possible reasons for this:
- When looking for answers, they do not log in anymore, especially many new users do not know or care about accepting an answer
- After asking the question, they solved the problem themselves; often asking a question lets you help to see your problem more clearly, especially for people who ask questions very hastily without doing a lot of research, or even thinking beforehand
- Something else might have happened - the person suddenly lost interest, the project the question was about was cancelled, their grandma had a car accident; there are million reasons for people not being active
Also besides not answering at all, when I ask a question, I usually have thought about solving that myself for most of the day, and I will typically ask the question before going to lunch or going home. So you will usually not get immediate responses from me as well.
after that they're not looking at the answers at all
- how do you know?
