Today, I gained +60 reputation points. The majority of these gains were from numerous questions/answers I wrote quite a while back.
I did not have this type of gain in any day of the past few weeks, especially not from such a wide variety of questions/answers I wrote.
It also just so happens that today I joined Stack Exchange Academia, asked a question there, and answered one question here on Stack Exchange Physics. Does this have anything to do with my unexpected gain recently? Does the website make my questions/answers more accessible if I show more activity?
