Today (at least I just discovered it today), Google launched a new service called Hot Trends, which is a part of Google Trends.

It basically lists down the top 100 searches for a certain day. However, it does not list down the top searches per se. According to Google Blog,

Hot Trends aren't the search terms people look for most often -- those are pretty predictable, like [weather] or [games] or perhaps [myspace]. Yes, [sex] too. Instead, the Hot Trends algorithm analyzes millions of searches to find those that are deviating the most relative to their past traffic. And the outcome is the Hot Trends list.
