It will take days for your site to be added into their database. Just sit back, relax and blog. The spiders will crawl to your site via links... you do have people linking to you don't you?

Or, if you are using Wordpress, you can try the Google Sitemaps plugin. Google for it.

You can propose some sort of links exchange with some friends or similar blogs. It can be a good way to provide alternative content to your readers.

Don't worry about the spider not mapping your blog. It's just a matter of time. (and it won't be too long either)

What's more, you are hosting off blogger. Google owns blogger and your blog should be cached/listed/mapped/any-spidey-related-terms...

Think of it as a spider crawling through the world wide web searching for keywords. Different search engines have their own spiders and they rely on them to do the caching for them.
