That's not a timestamping service; that's just a way to quickly notify Google when you add a page to your blog.
What if your blog doesn't use Pubsubhubbub, but mine does, and I copy your blog post? Google will see my post first, but that doesn't prove I wrote it, so Google cannot use that to make ranking decisions.
- thaumasiotes 11y agoI don't see how pubsubhubbub differs from the originally proposed timestamping service. For any timestamping service, it will still be the case that if you don't use it, and somebody else scrapes you and does use it, their timestamp will be better than yours.
- nitrogen 11y agoThere can be more than one timestamping service.
- nostrademons 11y agoThis is not an advantage. Imagine a scenario where a rogue timestamping service performs just well enough to get a significant userbase. They then alter their service such that instead of simply returning the timestamp, they put the content up on the Internet, but assign themself an earlier signed timestamp before returning a timestamp to the original requestor. They would instantly replace all of their customers in Google results, because Google would think that they were the originators of the content. They'd then be free to do all sorts of mischief with that influx of traffic: show ads, install malware, phish addresses, etc.
