Here I present two simple ratios:

answered questions over total number of questions (ANTO)
accepted answers over answered questions (ACAN)

A very crude measure of quality of the forum could be the convergence of the two ratios to 1.

The ratios are correlated by construction but it's interesting to observe the delays in the adjustments and to monitor deviations from the optimal path.

% Create axes

opt = {'EdgeColor','none'};
x   = [time1455(1); time1455; flipud(time1455)];

% Fill ANTO to 100% line

ynan    = isnan(y);
y(ynan) = y(find(ynan)-1);
fill(x, y,[.988 .659 .627], opt{:});

% Fill ACAN to 100% line

% ANTO trend

% ACAN trend
