Yahoo’s MyBlogLog, which powers the recent reader widget seen on many blog sidebars (including ours) is releasing an API. The API currently in private beta, will allow developers to query MyBlogLog Users’ social networks and pull the meta-data associated with their profiles. How is this significant? Imagine of being able to capture and use the names, ages, genders and blog interests of the people who visited your website. Even better, how about being able query their friends, and their friends friends . Imagine the marketing and research implications. For an in-depth read on the Significance of the MyBlogLog API check out our good friend Marshall Kirkpatrick’s post over at ReadWriteWeb.
