This struck me too, the fact that this task is so impossible.

Language changes in the time axis but also in the location and social axes. The best we can probably hope for is one snapshot in time. However this is meant to be a blogger, journalist, writer etc., through time this may have been the expected style for writing of this sort.

Especially in medieval times, I understand it may have been impossible to understand people a few towns away as the dialect could change so dramatically.

Disclaimer, I'm no expert, but I find linguistics fascinating.

Still, I really enjoyed this and I commend the effort!
