Google Page Rank 0

I once asked my friends why is my pagerank in google toolbar shows a "White Blank"
b4 it used to be grey
my friends said its some kind of error
i assumed that maybe my blog has been indexed
and today i gave a search on google regarding this google page rank 0 thing and came
out with some results
i ll show u

"The white bar has several and different meanings, not only one:

* PageRank value is not yet calculated because it is a new page.
* PageRank value is calculated BUT it is not display on the Google toolbar. Read our article: New Google Dance but still no PageRank update:
* If your page used to have PageRank but not anymore it means either:

* your page is banned by Google (hand penalty is made by Google employee)
* your site was down when Googlebot last crawled your site
* your page is considerated as duplicated content by Google

Sometimes you may find a grey bar. This happens only for the pages still not indexed in Google."

"A PageRank of 0 does not always mean a penalty. Sometimes, websites which seam to be penalized simply lack inbound links with an sufficiently high PageRank. But if pages of a website which have formerly been placed well in search results, suddenly show the dreaded white PageRank bar, and if there have not been any substantial changes regarding the inbound links of that website, this means - according to the prevailing opinion - certainly a penalty by Google."

i wish my blog has not been penalized :(
