A colleague sent me the link to Wired's article named Google Maps Mashup Documents Libyan Protests. Here's a direct link to the map. Libya was also one of the countries getting an high resolution imagery update in Google Maps a month ago.
From the map's information: "This map has been created by compiling reports from trusted accounts on Twitter. Nonetheless, these reports are in general unconfirmed. This information should be considered in the context of there being absolutely no independent media in Libya at this time. This map is not automatically produced. Each posting is considered before it is mapped. These considerations have evolved over time as conditions on the ground have changed."
