This means the success of your article falls down to the whims of the few people browsing `new' at any given moment. If you're lucky, there are people interested in your topic there; if not, your article might easily fall through the cracks. Moreover, since `new' has a very bad signal to noise ratio, most people do not spend very much time there. I certainly don't! So this means it's even more likely for an article to fall through the cracks there.
For better or worse, this means HN misses out on good articles as they fall through `new' without getting votes. To get anywhere your article needs to be both good and lucky.
That gives a chance. If the community doesn't like it it won't stay up, but it gives you at least a chance.
BTW I don't see any mention of this in the rules.
HN: Lots of false negatives, few persistent false positives.
The twitter notification part broke at some point (I haven't had time to fix it), but the main chart is surprisingly accurate. It shows that it's been a good time to post for the last hour or so, so this submission was very well timed. That other submission was sent at a particularly poor time (about 2 hours ago), when few people were upvoting on the new page.
Timing really does make a big difference.
