Switching between timelines and/or comparing metrics over time
When I click through to something like “Visits” to see that plotted over time, I currently have to go back and then click through on something else like “Posts” to see that plotted over time.
It’d be nice at minimum to be able to switch between those two once I’m looking at a graph. Better would be to see things plotted on the same page to get some insights into how things are correlated.
Reading metrics
How much people are reading seems like one of the most fundamental 
things we should be measuring.
We’ve started to play around with better ways to measure this and so far, something like this is looking promising:
Number of Users who have read at least N Posts over 28 day periods
Writing metrics
We are also exploring measuring writing activity similarly:
Number of Users who have created at least N Posts over 28 day periods
We chose 28 day periods because we see activity varies considerably with the day of the week. So choosing a period that always includes the same number of Sundays seemed like it might be a good way to handle that.
In both reports, the break points in our data explorer queries for each “bucket” are powers of 2, but in the reading case, we collapsed some of them to simplify the visualization.
