The Google bot is crawling the pages because they are cached. Have you tried getting deeplinks via dofollow bookmarks?
I just did this trick to another blog of mine but same is the issue there as well.
The homepage is the static page here. I just posted a new article and its showing the title in the search on the frontpage but not the article.

The third result is cartuningpoint.com home page which is showing the title of this article. Same is happening to all of my blogs. I even changed the server but no benefit. Its not about time, because same is happening from the last 12 days.
Well... I while ago, I was doing social bookmarking stuff but that led to another problem so, I quit that. Should I do that again?
I do bookmark my links on Facebook and Twitter though.
