All that is likely to change when microformats get more support in the browser. Even a non-savvy user can use them if Firefox has an "add to address book" button. And Firefox 3 will have native microformat support.

The short of it is that it's good to have for the savvy net user, and it could be good for the non-savvy ones in the future. Plus supporting it is really easy, so why not support it anyway?

Hello Andy,

Thanks for commenting, and to clarify it .. actually most people i know (online / offline) can be considered as non tech savvy users, while for some tech savvy users it can be considered as useful feature / addition

a good example is from your comment like the hCard microformat, most people i know isn't using the Address Book they just simply use copy from the webpage they're viewing and then paste it into their favorite text editor (from notepad to excel), even those who's can be considered as tech savvy users still prefer to use the old copy paste method

If you mark up your contact details with the hCard microformat, I can add them directly to my address book.

If you mark up your event details with the hCalendar microformat, I can add them directly to my calendar or diary app.

If you mark up a list of coordinates with the Geo microformat, I can pull a KML file from the page, and see them overlaid in Google maps or Google Earth.

What's not useful about that?
