Maybe. I haven’t seen any evidence as of yet, but it is early. Also, the effect of followers/clout upon karma is pretty conservative. Another way around that is that eventually, I expect that people will be as interested or more interested in their hubfeed, rather than the front page. If it gets busy enough, I might exchange the two as the logged in home page.

Do you have any ideas why it might get gamed in particular?

(BTW, did this story get frozen at 5 votes? It got there quick and then died. :/) EDIT: I guess not. 6! :)

Every site with karma is gameable.
