This is probably a question I should answer myself empirically, using an API or a data-dump. It's a generic enough question that it may have been answered already.
My SO rep is a paltry 5k or so. Due to competing pressures, I've dropped off my engagement in the community in the last few months. I've probably asked very few questions in that time, and answered a similar number.
Despite almost never contributing in that time, my previous questions and answers have accrued several hundred reputation points, and several badges.
This passive increase must be an inevitability; it started me thinking about interest rates and inflation.
So here's the question:
- on Stackoverflow, what is the interest rate? i.e. if you stopped posting last month, what would this month's increase in rep be, relative to your current rep be?
- is this "interest rate" constant, or does it scale with number of rep/number of questions/number of answers?
- for other Stack Exchange sites: what other factors govern this interest rate (e.g. size of community/total number of questions/age of community).
I'm in no hurry to find the answers, but I thought it interesting enough to ask you folks here.
