This question should actually be generalised to all answerers regardless of reputation.
In your post you mention the inconveniences from the asker's perspective. I will come back to this but I think it is fair to also consider the answerer's perspective:
- Has the asker provided enough context in their question? In particular, does it allow answerers knowledge of the asker's level or ability?
If there is insufficient context, such as a problem-statement question, it would be impossible to know the asker's ability and at which steps they do not understand or cannot proceed. Therefore, if you wish to ask a question, make sure to provide the motivation, your attempts and/or your level. Currently, Enforcement of Quality Standards aims to mitigate this issue.
- Answerers are volunteers. Do they have enough time to answer to further requests?
Users on this site may have more important commitments. Sometimes it may not be possible to provide further detail for a certain period of time. Since you say that those users were in fact active, I will now take the asker's perspective:
- Why are answerers giving such unhelpful answers?
If you find an answer too short to be helpful, you can leave a comment under their answer. If it is too unhelpful or low-quality, there is the option to downvote, and in extreme cases to flag as a low-quality answer. Repeated offenders will be given warnings and suspensions.
- Why are answerers unwilling to respond to my comments despite being active elsewhere?
Some users may simply choose not to respond as they may find the discussion boring or unproductive, and may be onto another question that is more appealing to them. I should stress that again, all answerers are volunteers and are under no obligations provided that they adhere to basic Stack Exchange guidelines. I believe that it would in fact be counterproductive to warn or suspend answerers solely on the basis of not responding to comments. This would be overmoderation.
- What can I do to resolve my queries?
There are several options. You can wait and hope to see if other users will answer your question in a more detailed manner. This can be aided through placing a bounty on your question and leaving this message to future answerers. This can also be aided by editing your post with considerable improvement to attract attention, but I must warn against excessive or superficial editing with the mere purpose of bumping a question. Lastly, you can post a separate question asking for a more detailed discussion of your previous question, but ensure that it is linked in your new post.
