What you're describing seems to me exactly what I was getting at. I bet if you try a good two hours of sharing, posting, and commenting, you would start to see things turn your way. Besides, the more one posts, the better the chances become that they'll be shared. I don't want to suggest that you, or anyone else, should do this willy nilly though. I say, if it isn't in your nature to post and share lots of stuff - then so be it.
One thing I really enjoy doing is finding something in one community, sharing it with another, and then comparing the discussion that results. It absolutely fascinates me. With that in mind, I've become exceedingly good at crossposting things between different subreddits, so it's not that much of a leap to continuously share things with the hubski community as I find them in my daily redditing. Right now I'm pretty much dividing my online time 50/50 between reddit and hubski, which is impressive if you know how heavily invested I am into reddit.
