Google has a very interesting and ever changing algorithm. Thus, pages with new content may get indexed much more than statis ancient pages but there are other nuisances as well. http://www.google.com/webmasters/

To improve the indexing process you should make sure there are some links pointing to your domain. Googlebot works like a spider - visits websites and continue spidering the links on the page. This means that Googlebot will not index your website until there will at least one link pointing to your domain name.

Takes time...
My blog posts usually appear in search results almost immediately, but are 100% indexed in 2-3 days (info from webmasters tools)
