. With the mass roll-out of its newly-introduced "Open-Graph" protocol , Facebook has greatly extended its capability to collect personalized web traffic data by freeing the oh-so-tempting and easy to use "Like" button from the confines of your Wall to more than 50,000 of the most frequented sites (and growing) on the web. It will be interesting to see if Facebook's new features will pose any issues in how Google tracks web traffic, or if it has the potential to upset its page-ranking algorithms, and what Google might be planning to do about it... In the recent write-up "Google's nightmare: Facebook 'Like' replaces links ", some interesting points are made that highlight how this new functionality challenges the search engine giant where the bread meets the butter. We want to know what you think. Is this a big deal for Google? Let us know in the comments.
