[tantek] the only prior art I know of of an actual cross-site tagged post aggregation service was Technorati Tags, which was based on rel-tag linking to category URLs but on *any* domain, you did NOT have to link to the Technorati tag pages (the way indiewebxyz required you to link to indiewebxyz "subs" in order to be aggregated into them)
