Quite a few announcements yesterday from Google one of the most important has to be the one about Social Search -launched on google labs that is based on the “social graph” principles whereby all friends and associated content within your cirlce should provide a more relevant source of results:-
“(..) a new feature that allows you to see results for queries from people in your social network. This works by using your Google Profile. If you fill it out with the other social networks you’re a member of, such as FriendFeed, Google will scan who you are connected to and give your results from those people.”
This opens up a whole new area to certain sectors especially travel and I will let Kevin May over at tnooz explain it in detail, it also has a major impact on SEO and how people get the best results and act on them something that is discussed here on huomah.
