Sites to check
The following sites may have rel-tag and need to be checked and placed into lists on rel-tag-supporting-user-profiles as well. Feel free to add icons/logos for each of these as well.
search engines as rel-tag namespaces
Some search engines provide searches with rel="tag" compatible URLs, e.g.
If other search engines can add such compatible URLs, then they too could be used for rel-tag links, e.g.:
- A Google search for 'microformats' resolves to http://www.google.com/search?&q=microformats
- Google should also accept http://www.google.com/search/microformats
- Twitter Search (formerly Summize)
- Yahoo Search
