Using data explorer (e.g. this), I generated the following plots which show the per-day number of questions and answers, and upvotes and downvotes. (The moving average is over a 30-day period.) I also include a plot of the number of questions and answers with a given score.
Edit: I now include the weekly number of comments, question votes, answer votes, new users, active users (using this query).
I include this as a reference post for the future, but I'll put some comments below:
I speculate that Islam.SE is not far off seriously being considered for graduation...
At meta.SE, Ana writes: "When a site starts to consistently receive 10 questions/day, we’ll consider it for graduation." We are currently listed as 8 questions per day at Area 51, although I'm not sure how reliable that is. Looking number of questions each day thus far this month:
date (Feb 2017): 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 no. quest. 3 4 7 5 9 9 7 15 1 7 7 6 9 10 13 7
I'd say we're realistically around the 6 to 7 questions per day mark. To put this in perspective: Philosophy (Area 51) had 5.7 questions per day when it was launched 7 months ago. Christianity had 3.9 questions per day when it launched 3 years ago (Area 51) and Mi Yodeya had 6.6 questions per day when it launched 4 years ago (Area 51).
The decreasing number of upvotes and increasing number of downvotes is a concern. Edit: However, the figures suggest we've been recently getting an increasing number of votes on questions and answers, which is encouraging.
It indicates an increasingly unfriendly attitude at this site. At some points the 30-day average downvotes outnumber the upvotes, which indicates (a) the content posted at the site was predominately poor, and/or (b) the users of this site were more interested in downvoting poor posts than upvoting good posts. Either way, it's a bad sign.
I get the impression that people are desensitized to downvotes. They don't react to them because they're so common. (Edit: Probably I'm wrong about this, and it's more complicated than what I thought; see goldPseudo's answer.)
How are we going to convince the StackExchange team that we have quality posts at Islam.SE if we're not upvoting them?
In 2016, there were 7 posts with a score of 10 or more
score:10 created:2016(compared with 103 for Christianity.SE; 103 for Judaism.SE; 17 for Buddhism.SE; 82 for Hinduism.SE).
In fact, 70% of the 321 StackExchange sites (including meta sites) did better than this (data explorer query):
Except for ExpressionEngine.SE (with 2) and Patents.SE (with 0), every launched site had more than double the number of 10+ score posts in 2016 (the next lowest was DSP.SE at 15).
The new per-week figure shows the number of new users per week is increasing rapidly (going from 41 in January 2016 to 78 in January 2017), which is exciting! While the number of users growing faster than ever, the number of active users does not appear to be increasing (although, maybe earlier data is influenced heavily by Ramadan).
Any other lessons to be learned?
By the way, there are three posts from 2016 on 9 votes:
