Microformats
Microformats are a fantastic idea!
Think of them as a tiny subset of information to be exchanged. Some of the most popular micro-formats include vCard, hCard, hResume, hCal, … anyway, you get the idea. Whenever you want to share the details on someone, some event, or just a contact – micro-formats are probably the easiest way.
When ever you create a new web site, thing about the pivot use of your data or user data. How can someone else use this data? How can the user re-use their data someplace else? Is there a way/desire to connect data from your site to another site(s)? If there is, find a microformat and use it!
