Discourse statistics?

Meta Discussion
1

Out of curiosity, is there any public stat on discourse activity? Like posts or new users / month or stuff like that?

Hereā€™s the data in graphic form

activity900Ɨ800 170 KB

and hereā€™s some code if you want to play around yourself

using CSV, DataFrames, DSP, Plots
default(show=false)
data = CSV.read("/home/fredrikb/Downloads/daily_activity.csv", DataFrame)
sort!(data, :date)
data = data[200:end-1, :] # remove the very beginning and the current day

##
function mf(x)
    m = mean(x)
    # filtfilt(df, x .- m) .+ m
    filtfilt(ones(14), [14], x .- m) .+ m
end

fields = ["users", "posts", "pageviews", "likes"]

figs = map(fields) do field
    x = data[!, field]
    x_filt = mf(x)
    fu1 = plot(data.date, [x x_filt], layout=2, sp=1, title="Daily new $field", linewidth=[1 5], lab=["Daily" "2 week mean"])
    plot!(data.date, cumsum(x), sp=2, title="Cumulative $field", lab="")
end

plot(figs..., layout=(length(fields),1)) |> display

Could the trust level to access the stats be lowered to ā€œmemberā€ (if not making the stats completely visible to everyone) ? There could be some sensitive data on these stats ?

In any event hereā€™s an update:

Note Iā€™m not a signal processing expert like Fredrik so this is a more pedestrian 2-week running mean:

julia> using CSV, DataFrames, Plots, RollingFunctions

julia> data = sort(CSV.read("discourse.csv", DataFrame), :date)[200:end-1, :];

julia> ps = []
Any[]

julia> for (v, t) āˆˆ zip(["users", "posts", "pageviews", "likes"], ["Daily new users", "Daily new posts", "Daily new pageviews", "Daily new likes"])
           p = plot(data.date, data[!, v], label = "Daily", lw = 1, alpha = 0.5, title = t)
           plot!(p, data.date, runmean(data[!, v], 14), label = "14-day average")
           push!(ps, p)
       end

julia> plot(ps..., size = (800, 700), xrot = 75)

Decreasing trend in likes per day suggests @Tamas_Papp has been less active over the last yearā€¦

The one metric missing from the original post and my post above is topics, so here for completeness:

Indeed it seems like likes have declined the most out of all metrics, which is probably the Tamas effect. At the same time pageviews is the only metric with an entirely unbroken upward trend, so maybe thereā€™s more and more people out there who find Discourse through a web search and get the info they need without ever having to sign up, post, or like anything.

Thereā€™s no sensitive information here ā€” if there were we wouldnā€™t make it available to anyone. It does, however, make sense to limit its access for both community and server load reasons. Itā€™s an expensive operation that we donā€™t want lots of folks to run, and generally the folks who are most curious are those who are most invested in the community.

Edit: there are some basic statistics available in the about page: About - Julia Programming Language
