Why won't my website get indexed? (Answers: 3) (Comments: 0)

This is my website: www.billigaconverse.com I've written a lot of content in it, and I don't know how many times I've pinged the website. I've used ping tools like pingler daily. I've also linked to the website from a PR 3 blog of mine. I also wrote some articles about the website, and linked to it in some words, but still... my website does not want to get indexed. There has been one page that has been indexed, and that's the "main page" that got indexed BEFORE I made any changes. As soon as I bought the domain, the site got indexed. Two days ago, I added about 10 pages of content, changed design, and performed great SEO on it, but still... the search engine spider won't visit my site and crawl it! I've submitted my sitemap to Google Webmaster Tools, Yahoo! Site Explorer and Bing Webmaster Tools. Bing & Yahoo! already indexed my website, but Google just won't do it. I don't know why. What more can I do to speed up the indexing? This is driving me nuts.
