1. Search - There is no doubt search engines are the dominant tool for finding information online. More recently, the search for meaning is about more than using powerful algorithms to offer hundreds of thousands of search results. The social search revolution is about how people are helping other people find information. The most innovative Web2.0 tools for search are the ones that combine sophisticated algorithms with the ability and dedication of individuals to help highlight, describe and categorize information.

2. Discover - If search is about actively seeking information on a specific topic, discovery is about uncovering information that is likely to be relevant for you presented to you based on your browsing history, habits, related content, or relationships and declared interests. The popularity of StumbleUpon as well as the millions of people using social bookmarking tools such as Digg and del.icio.us point to the rising use of sites, tags and recommendations to discover new websites or web content.

3. Connect - Managing relationships through contact managers such as LinkedIn is not a new activity online, but there are new tools that are helping each of us to get smarter about how these contacts are managed and make them more useful. A core concept that Hunt talks about which is now starting to appear is the idea that not all relationships should be treated equal and there needs to be a way to rate the strength of a particular relationship.
