(*)"Engaged Users" are those that do not have reputation $1$ or $101$, i.e. those that had at count day performed some reputation-affecting activity on the site (I count out also the $101$'s because the $100$ points are SE-registration bonus if they are active on other sites). I decided to show "engaged" rather than "unengaged" users, since all other metrics in the table have the association "larger value = better".

COMMENTARY
For the first time in these 150 days the numbers gave me the impression that it is picking up speed.
Q's/day and visits per day have visibly increased while the rate of new registrations per day is unbelievably constant during all these 5-month period (7-9 new accounts per day, month per month). But this means that already registered users are becoming returning customers at a higher rate-which is critical.
Moreover the "% Answered" and the "Answers ratio" hold, despite the increased rate of new Questions -which also means that contributions keep up with the incoming flow.
In light of the above, the "Avid users" metric, although still the most serious threat in my opinion, worries me less now than 30 days earlier. But that's most probably psychology, a framing effect -and as economists we should know better than falling victims to framing effects.
So keep worrying -and keep up the pace.
