Linux is down slightly after a peak month, but probably that month had Linux over-represented. This month we see English down a bit too, Chinese is up a little.

I copied the data from gamingonlinux and put it into my own sheet with an exponential trendline (red) and a moving average line (green) to smooth out the variance of the survey. We’re definitely trending upwards.

Here’s the csv data
0.78, 0.72, 0.80, 0.82, 0.82, 0.77, 0.82, 0.81, 0.84, 0.76, 0.79, 0.80, 0.83, 0.83, 0.81, 0.83, 0.90, 0.83, 0.87, 0.89, 0.91, 0.88, 0.86, 0.89, 0.94, 0.90, 0.90, 0.78, 0.91, 0.81, 0.85, 0.85, 0.86, 0.89, 1.00, 1.02, 1.05, 1.13, 1.16, 1.11, 1.06, 1.02, 1.00, 1.14, 1.12, 1.18, 1.23, 1.27, 1.23, 1.28, 1.44, 1.38, 1.38, 1.27, 0.84, 1.32, 1.47, 1.44, 1.96, 1.82, 1.63, 1.39, 1.91, 1.97, 1.95, 1.76, 1.94, 1.90, 2.32, 2.08, 2.08, 1.92, 1.87, 2.00, 2.03, 2.29, 2.06, 1.45, 2.33, 2.27, 2.69, 2.57, 2.89, 2.64, 2.68, 3.05, 3.20, 3.58, 3.38, 2.23, 5.33, 4.52


I considered it, but we’re so early in the exponential rise that I didn’t think it would matter significantly unless you really wanted to do some future extrapolation
