Re: But wait!
Article 11: The link 'previews' that are usually generated on the 'aggregators' are set by the publisher in their web page meta tags.
Where does that come from?
I included that feature in the original WebÞing back in 1995. A couple of years later, spam started to become a problem, and it became clear that it was only fit for a closed system whose participants shared a reasonable level of mutual trust. A general-purpose search engine like google would just be handing itself to spammers if it used those.
