Nathan Weinberg of Inside Google received a tip from a "quality tipster" that could possibly be related to my post about Google Checkout yesterday. In his article, he says that Google is holding a closed beta (probably to trusted testers) that helps people make purchases from "high quality" merchants.
Like many people have said in reference to my last article, all we know is that Google registered "googlecheckout.net/org/info" -- this doesn't necessarily mean anything. Google registers domains all the time, but they aren't obligated to do anything with them.
My speculation is based on the registration of that domain, and what I think the domain could be used for given current events and what would make sense. "Who f-ing knows! It's just a domain name for crying out loud!" as Garrett French states in his article at Search Engine Lowdown.
