That's what a bot would say :) I'm not sure how HN's ranking algorithm works, but it seems similar to Reddit where there is a velocity factor. So all you need to do to boost your submission on to the front page is a decent submission and a few upvotes in the first few minutes. Then it's on the front page and organic votes will keep it there. Of course they have systems in place to prevent it, but it's an arms race.
EDIT: can you remember how many upvotes it had when you voted?
It showed a score of 1 (no upvotes) when I clicked to read the article. Then after approximately 2-3 minutes of reading, I clicked back and upvoted without refreshing, so I don't know how many votes it had when I actually voted.
