Dude, I haven't looked at all of your content - but when you produce web pages like the one of the ancient kingdom of Fife that you did - stuff like that (very high quality) is the cream that rises to the top.
The people that run reddit.com seem to literally hate me - so they won't let me have a real account - or I'd put some of your hubs there myself. My advice is to put your hubs on reddit. . . .but if you only share your hubs, they'll eventually hate you there like they hate me.
But reddit drives more traffic to hubs than any other site that I know of.
Are you on Facebook? Facebook groups are sometimes good to great sources of traffic. I created a FB group that . . .sometimes works out well, and the dozens of wordpress bloggers that are in it.
Newsvine is another decent site to join that you could use to drive traffic to your hubs.
