Several more announcements around the Web 2.0 Summit focused on search yesterday, in ways that will be relevant to the music industry. The first trend is real-time. Twitter has signed deals with both Google and Microsoft to give their search engines full access to its feed of public tweets. Besides allowing both Google and Bing to provide search results of what people are tweeting about in real-time, they’ll also be able to index the data and identify trending topics and links. The second trend is social. Google has also announced plans to launch a social search engine, which will show users results based on what their friends have been doing online. It cites the example of a search for ”New Zealand” which would bring up travel reviews and photos from friends who’ve been there recently. You can imagine how music fits into this, though – particularly if it also ties in the features from today’s Top Story.
