MicroID, for the uninitiated, is a snippet of code (which is made up a user’s email address and the URL of the current web page) which can be used by machines to verify the owner of the current web page. As a user, I find it incredibly annoying to tell the multitude of sites I use what other sites I use. (“You’re a computer,” I say. “Figure it out.”) As more sites roll out MicroIDs behind the scenes, pages/profiles I author (or am somehow responsible for, such as my YouTube Favorites links or my Amazon Wish List) could quickly be “sniffed out” by sites I already use.
Why would I want them to know what other pages/sites I use? I answered some of this in my interview upon joining YDN. But, quickly, it boils down to a decentralized and lightweight trust system that would allow the software behind any site at which I’m recognized to provide relevant content/recommendations. That, and I wouldn’t need to spend any time sharing all my other account usernames with a site I’m not even sure I want to continue using.
(Side note: As some may know, I had the good pleasure of working closely with the MyBlogLog team for the first two quarters of 2007. Aside from getting to getting to work on a new version of the Recent Readers widget and the all-new Profile widget (among migrating to the Yahoo! ID and the common Yahoo! profile representation), I got to work alongside some of the incredibly talented crew: Todd, John, Steve, Chris, Robyn, Ian and Eric.)
