Jacques, perhaps you could configure your blog so you can choose to submit your own posts automatically to HN when you post them? That might reduce the tendency of people to try to rush and post them first, assuming the majority of posts are actually suitable for posting here.
I don't think you should worry too much about it either. Your posts seem to keep gathering a high number of votes whenever they appear on HN, so this is a sign that they are useful and relevant to the community. If an irrelevant link gets posted and it only gathers a few votes on the new page, then what have you lost? What has the community lost?
The problem is that if just 3 people auto-submit the post in the first minute, it's immediately at the top of the front page. Often, many people will reflexively upvote something by jacquesm, so the result is that a top slot on the front page is taken up for some time, perhaps by something that's not really worthy of discussion. This takes away attention from other, more worthy posts. There are only 30 slots on that front page.
This used to happen with 37signals too - I'm glad to see it stopped happening there. Time to stop autosubmitting jacquesm as well!
Ah yes, I had forgotten that resubmission counts as additional votes. I agree - it's not an ideal situation if posts get on the home page purely from automated submissions.
I understand your intentions but I don't think that's a good solution because it will still submit items to the 'news' page that are not always 'up to standards', giving them at least one upvote. That's roughly 25% of what's needed to get an item to the homepage, so only 3 more (bot)votes and it's done, once an article hits the homepage it is likely to stay there for a while. All this would do is add one more bot to the race and thus increase the problem.
Not having those items on the 'news' page would seem to be the best solution.
Really, people should at least read the articles they submit and judge them for content before submitting them to HN, especially when they're associated with the better known (ex)HN'ers.
Probably Sivers, Patio11, Tptacek or any one of the people that seem to be featured a lot here could write an article about 'Condé Nast acquiring HN' (in a desperate move to re-acquire Reddits' audience that has left for HN, thereby realizing the fears of all true Hackers, the proof that this would make 'HN more like Reddit' is left for the reader) (there goes my April 1 post ;)) and it would get upvoted without much consideration.
One possible (technical) solution would be to let the karma boost be dependent on the average of all posts from a domain, submit a 'below average' link and your karma will drop!
I've discovered an elegant proof that HN is like Reddit, but ... oh, darn, that doesn't work online.
Maybe submission upvotes in a short time shouldn't front-page an item. I don't see why not putting these links on the news page should make a difference - if anything it would make it impossible to get non-bot upvotes, if I understand what you mean.
It is interesting that you have the reverse problem of most people that want to draw attention to things on HN. Maybe you should start selling guest spots on your blog :P
