Subfolder get sanboxed?

Hi guys,

I don't know what's going wrong with google.
I have a website with nearly one year old. Four days ago, i created a new subfolder and install wordpress on it.
I pinged the site, rsss, bookmarked, create profile in identi.ca with the homepage points to my new built subfolder.

until now, when i search the tearm "http://mydomain.com/mysubdomain". There is no result on google.
Not talking about subfolder get indexed but even the text links i put in famous sites are not recognized.
Normally, i takes me only few hours to see my "http://mydomain.com/mysubdomain" on serp in sites such as jumptag, identi.ca after creating.
Can this be the new face of google?

please, someone can explain this?

foget the thing,and go on build some page instead

that means I should forget my page? but the question is can my subfolder get sanboxed? It's really strange that google didn't even recognize my url text in bookmarks pages.
