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!"
