I was browsing Arqade today and saw this question, What are the differences between the Wii and Xbox One/PS4/Switch versions of Just Dance Games?, became active today (1/31/21). I am curious why it is active if the last comments/posts are from a year ago. I looked at this question on Meta, Why are some posts marked as highly active and others are not?, and saw they could be protected because of deleted and low-quality answers. Since I am not at 10,000 Rep, I would never know this. How would someone like me know why a post became active?
While researching the Meta Active Question, I stumbled across this question, Do we really have 1.7k late answers to review?. I have been hesitant to answer questions that are older because (A), I don't want to burden the Moderators and higher-rep people with an answer to an old question; and (B), If I post an answer, and someone doesn't review my answer, does it just get lost in limbo, never to be seen by anyone else?
This is my first Meta post. Please let me know how to improve, and feel free to edit my question!
