It's a shame there isn't more activity in the history communities.
On one hand, on another hand... Yes, but thats life.
Most of the folks on the blockchain are authors / content providers, not readers; and they after rewards. This is the way I see it.
Making 5-10 captures on your smartphone and getting a fat reward for your lazy-effort-no-ideas post is far more profitable and time-saving, than working hours or even days on putting together an intresting story, condensing unique personal thoughts and experience -- which, lets face the truth, may get tiny or even zero rewards. Thus, most hiveans' choice is obvious. Grass grows better where it is watered and fertilized :/
As for me personally, I am pretty obsessed about history (and could share a lot of interesting stuff from the books I was involved in, or video lectures I've watched), but firstly - see point one, and secondly: most likely, it will be of interest mostly to the Russian-speaking public than the English-speaking one...
