There's no cache for my blog, after redirecting to a ccTLD!This is an example of the confusion, from a concerned blog owner.
99% of all Blogger blogs will see no difference, in indexing or reputation, to their blog, in Blogger / Google services.
Every BlogSpot published blog, which uses a standard blog header, has a "Canonical" tag, defining the "BlogSpot.Com" URL for that blog.
Search engines which recognise the Canonical tag will simply index all BlogSpot content, whether accessed as "blogspot.com.au", "blogspot.in", or whatever new CC TLD alias is deployed in the future, under the base URL, "blogspot.com". Blogs such as this one, published outside "blogspot.com", will continue to be indexed under the current non BlogSpot URL.
<link href='http://blogging.nitecruzr.net/' rel='canonical'/>That's the Canonical tag for this blog, "blogging.nitecruzr.net".
When you check the Page Rank, you should continue to check the "blogspot.com" URL - if your blog is published to "blogspot.com".
Some non Google services such as Alexa - and some third party accessories such as commenting, provided by Disqus and Intense Debate - are known to require tweaking of their code, so they will recognise the Canonical tag for the host blog. Once the code is properly updated, they should simply reference the host blog under the "blogspot.com" alias - no matter where the blog viewer may be geographically located.
It also appears that the Stats "Traffic Sources" display is displaying the different CC aliases, rather than aggregate inlinks using the canonical URL. This is causing some confusion with people who are not yet aware of the CC aliases, and their purpose.
The "Forgot?" wizard, on the other hand, uses only the blog name. Whether you are seeing your blog as "xxxxxxx.blogspot.ca" (in Canada), as "xxxxxxx.blogspot.mx" (in Mexico), or "xxxxxxx.blogspot.com" / "xxxxxxx.blogspot.us" (in the USA), you'll always use only "xxxxxxx" when recovering access to your Blogger account.
If your blog uses no third party accessories or services, relax just a bit - then get back to work on your blog.
