Google is very slow in indexing, even my blog is hosted by Blogger that owned by Google.
Actually, my Digg page http://digg.com/tech_news/CuocthiSEO_2 holds 8th place. That's good signal. Logically, original page should be ranked higher than Digg page for the same keyword, because theoretically Google loves original content, my blog is original and Digg page is only link to the page. However, I don' think that Google is too smart to understand that :D .
I expect that my blog should be index within this week.
For fun: I just tried to google a image with keywords "Stupid Google" and found this funny picture that says how smart is Google:
That's good, Google! :D
