I’ve been finding that to get listed at all on Yahoo I need to register for an account, add the page to a “my sites” list and add various feeds and maps into that. I’m also invited to authenticate my site. Yahoo generate a random value during an authenticated session and I am to add that to my meta tags.

Those measures immediately add an extra degree of trust to anything I publish on my site, Also, my Yahoo account is actually a personal account which is connected with my social network on Flickr and on Yahoo’s instant messaging platform. Therefore, a web of trust effect is being built up to validate web masters and any validation exercise applied to that web increases the degree of trust in the RDF data I publish. Unless and until I associate myself with evil spammers, I’m objectively trust worthy, and when I do, well more fool me.
