Thanks! The reason why I've separated is time - I thought it would be better to release them as I write them, rather than make everyone wait several weeks :)
I can definitely see it from your perspective: not only does it take less time to write one article rather than three [and probably less pressure as well!], it gives you content for your website (not to mention a steady stream of visitors wanting to see your content, rather than just one big group of visitors then nothing).
From my perspective though, it is unfortunate: I'm interested in the story, but I don't know if I will be interested enough to check back a few weeks from now to see the updates, perhaps because I forget the URL, perhaps because I don't see a post on HN about it, or perhaps because I just forget. I also think I'm spoiled by the internet: I want things now! :)
Solution: RSS! I'm a google reader user, and when I find things like this, I toss them in there. If it's not interesting enough going forward, I can always unsubscribe. Of course, if the author is using twitter/facebook/whateverelse to hype posts, you can use those to similar effect, too.
My solution is looking at integrating MailChimp's offering once the traffic's died down a bit. I should have done it before really, but am reluctant to further stress a server that's already getting a bit upset ;)
