You can speed up the process of getting into Google a bit, using certain legal tricks. I rarely do myself anylonger, but they might come in handy.
One is to put AdSense on. This is not official, but I've remarked very fast indexing just for putting AdSense on a site.
Another is to get incoming links to it, and there are several ways of doing that, which I had already planned for another blogpost.
So here I'll just write that you should use pinging-sites and social bookmarking such as del.ico.us, Stumble Upon, Digg etc. More details about that later.
Then there's the obvious – that you actually go to Google and add your blog. Click on All About Google and you can learn more about adding your blog.
