Quick thing for you fellow post-Redditors: The hubwheel next to each post is NOT an upvote/downvote button. It is a SHARE button. Don't click it to "like" a post. Click it if the post is meaningful, adds value, and would be of general interest to others on the site. It is a way to say, "Hey, you guys over there! Come here. You gotta check this out!" Not, "Yeah man! I agree with you!"
I'm guilty of this a lot. One way to think about it is the "share" button makes your hubski experience "more like this!" and for those that follow you, it makes their hubski experiences "more like this!" as well. It's fair to say that the "more like this!" feedback loop was the most instrumental mechanism in the isolation of the Laurelai influx. It's also fair to say that the reason I follow so few people is because overactive sharing is pretty much turning the volume knob up to 11.
