Add new metrics with focus on the active userbase

[Martinsos]

I am interested into what is the size of the userbase. Because 110 experienced users every day doesn't mean 110 active experienced users, it is more likely smth like 300 or 500 experienced users where each work couple of days per week, not every day.

Who qualifies as "active"? I would maybe say somebody who was active at least once in the last 2 weeks?
OK maybe just this: for each user that has been active at least one day in the last 2 weeks (so only "active" users, we ignore the rest), we calculate number of days they were active in total in their history. We then make a histogram, like 0-5, 5-20, 20-50, 50+ and see how many people fall in each bucket. That would be one report.
This doesn't distinguish frequency of use, or gaps (somebody used wasp intensely, then dropped it, then came back), but maybe that is ok, to keep it simple.

Ok yeah, so we have two things here really:

1. Define "active" user: user who was active at least once in the last 2 weeks.
2. Produce a report that groups "active" users by number of days they used Wasp in total.

Another metric/report that might be exciting to see is the frequency of use: for each "active" user, how many times have they used Wasp in the last month? Again histogram out of it. Oh yeah this would be interesting.
