This question already has an answer here:
A user asks a question to get an answer after a lot of research. They get the first answer, but it's not explained or detailed at all. As the asker did a lot of research on the question, he already understood the answer and therefore accepted that as the answer.
The user didn't get an answer anywhere else before, so this will be an important Q&A thread online.
Perhaps the questions without accepted answers may be the first priority for an answerer.
In the above situation, if the answer is not accepted quickly, then there may be more chance that the question will get more answers. So does the process of quickly accepting an answer degrade a thread?
If it is right, I'm suggesting a feature that an answered question gets more answers with the same importance shown to the OP.
