We've just added hcard in all iDOO blogs, you can have access to the author's hcard by visiting their blog, and interacting with it using the Operator plug-in for FireFox.
We have created an extension for the Operator toolbar (a Firefox extension to interact with microformats), which allows you import any hcard contact into your iDOOmail and contacts.
To use the script you will first need to download the Operator plug-in by visting the following link: https://addons.mozilla.org/en-US/firefox/addon/4106
Once you have installed the Operator plug-in You can download the iDOO extension here : http://static.idoo.com/labs/idoo.js and add it to Operator. You will need to save the page to your desktop and then use the Options->User Scripts to add them to Operator. After adding them, restart the browser.
This is the first step, but these are many things we are working on :)
