So far, I've seen rich snippets in Google search results only for large sites with a high number of elements (people, events, recipes, etc.).
Does anyone know of an example where rich snippets are displayed for a small site with only a handful/a few dozen elements?
Our own site has around 10 events (we are a specialized conference organizer) with rich snippet markup but so far they aren't displayed. To avoid misunderstandings: I'm interested in hearing about all types, not just events.
To clarify: We are using Google's rich snippet testing tool. Everything fine there.
