Getting back on microformats (see yesterday), I added my hCard to the bottom of my blog:
I will likely populate it a bit more soon (after holiday in Sweden).
Now, if you had the Firefox plugin Operator installed, you would have my contact information show up in your FF toolbar, like this:
Note the 'Export Contact' button in the toolbar. This will automatically create a vCard which I can directly open in my address book (I use the KDE addressbook). Very nice integration!
Now, I already asked the author how the plugin could be extended to support chemical microformats. Just think of the feature "Export Molecule (137)" (e.g. to Bioclipse), when reading a HTML version of paper in one of the Project Prospect enabled journals :)
