Digg.com publishing MicroIDs

In a post this morning, Digg announces MicroID publication on all their user profiles:

Digg already supports many of the open standards that let you use your data on sites other than Digg, including RSS, OPML, and hCard. We use RDF to embed the Creative Commons public domain dedication into each page. Just this week, we added MicroID, a Microformat that lets you prove to other services that you own your Digg user profile. We’ll be adding more open standards, such as OpenID, APML, OAuth, and XFN, in the coming months.

A big week for MicroID.
