Tips to increase Stacker News users (I thought of this recently):

Reddit has become really controlling. Mods ban you easily if you share a link to external sites. Go to the Bitcoin subreddit and try to link a post from here; users are so up that they downvote even without seeing it, and mods ban you for no reason. This method looks good. Users are frustrated and are trying to find a new place for where there is noo spam, like many have moved to Stack Exchange. I'm sure when they see Stacker News, they'll jump on it, just like I did.
