Did you do apply any spamming technique? I think your blog is in send box can you post your blog's link here
Use webmaster tools and check if there's any error message with the domain. It's usually due to black hat, but sometimes, hosting filters blocking googlebots IP's, or that having a wrong robots.txt file or a wrong robots meta tag, simple things like these, may cause it.
