You haven't come up with any pot of gold. This is quite common. I've seen google index my blog articles within 12 hours of posting them and then display new links to the same articles within 24 hours.
The days of waiting, sweating and worrying about when the spider will show up are over.
Yeah, I noticed this with my new blog too, though it was more like 5 days or so. I think what helped in my case was that I had a wordpress.com blog with the same title as my new self-hosted blog...but I could be just guessing here.
The nice thing about blogging is that you generate fresh content often, which attracts the spiders.
1: Never launch a new site with a lot of back links. Build natural links over weeks and months.
2: Register your domain name at least four months before you plan to launch the site.
3: Blog and ping carefully.
4: If you build bulk directory/portal sites - keep them in the 200-300 page range.
I really do think things have changed... If you do have original and interesting content then Google loves you.... I have been working on one of my sites for over a year and now everything I post ends up in the top ten in the search results within a few days... Indexed very quick...
I have made a new site with about 17 lousey pages and put a few links out there and so on...I was just about to submit it to google when I found out they had already indexed it.... I was shocked because it was always alot harder to get indexed..
My experience with Wordpress Blogs* is that articles appear in Google in about 20 minutes. So a few links in the blog will get sites indexed fast!
* wordpress blogs on your server - not on wordpress.com. Of course, could be the same for blogs on wordpress.com (??)
