I always wondered why are the answered questions reappear over the main page. I do know that we can filter question with given options, but this question was always on my mind. Example;

 - [How do I enable fancy apt colours and progress bars?][1]

I'm pretty sure there are valid reasons but all I could think of is reviewing the answered questions, newly added answers are acceptable, updating new information... etc. 

Well, maybe I'm too stupid to ask this knowing the answer. But however, I'm just trying to understand how exactly this benefits all the users and are they more meaningful answers.

On a related note, I couldn't find anything similar in here. Hence, the question. If there are any, please assist me finding it.
