Moderators have a view of the site's statistics, but they cannot share the specifics. So, I'm starting this post to keep track of the evolution of our statistics over time. Please feel free to update it every now and then:

I use the Area51 page as source for those stats.

Graph of the visits/day:

And here's the Quantcast estimate of site traffic, with a sparkline for the last 6 months, mean number of visitors per month, and highest and lowest daily visitor count in the last 6 months:

Why do we have historical Qs/day and Visits/day, but not A. ratio and Total users? – gerrit Nov 12 '12 at 13:29
@gerrit because I found those mentioned in a chat room message and in a meta post… but only questions and visits were quoted. – F'x Nov 12 '12 at 13:48
If I recall correctly, the answers/day has been constant at 2.5 for a long time. – Suresh Nov 13 '12 at 22:11
I think more people need to get involved. As of now its just a site to get your questions answered by 'a very select few' people. Not everyone answers questions here. Its typically 5-10% of the entire set of people who answer the questions. This is unlike other SE sites. – Naresh Dec 4 '12 at 6:55

@Naresh it is not that select for a beta site. We have 24 users with 2000+ rep which suggests that at least 24 people are/were regularly answering questions. – Daniel E. Shub Dec 5 '12 at 9:02

@F'x many thanks for your work in keeping this updated. It's great to see our progress – EnergyNumbers Jan 29 at 9:06

We seem to be in the green for everything except Q/day which is "okay". Does that mean we can graduate from beta soon? – Artem Kaznatcheev Mar 16 at 9:33
I have taken the liberty to add the tag "feature request". I hope that it is not going to far. I am surprised that these data aren't already available on area51. – Daniel E. Shub Mar 18 at 13:35
@ArtemKaznatcheev - See this answer for some clarity on getting out of beta. – eykanal♦ Mar 28 at 17:30
@DanielE.Shub - Unfortunately, that tag isn't going to get any attention here. Try posting it on the main SO meta site, which also serves as a general meta for questions like this for all the stack exchange sites. If you haven't posted there before, though, do note that they can be a bit rough on the newbies; they don't hesitate to downvote over there. Take it in stride :) – eykanal♦ Mar 28 at 17:32

I didn't want to make the post overlong, so I paste here the Mathematica code used to make the graph from the raw data (multiline string stored pasted in variable s):

t = StringSplit /@ StringSplit[s, "\n"];
time = ToExpression@StringSplit[#, "-"] & /@ t[[All, 1]];
values = ToExpression@t[[All, 2 ;;]];
DateListPlot[Riffle[time, values[[All, 2]]]~Partition~2, 
  PlotStyle -> Directive[Red, PointSize[Large]], PlotRange -> {All, {0, Automatic}},
  FrameLabel -> Style["Visits per day", 14]]
