Google Plus

facebook may not necessarily see google plus as an immediate competitor, but you can bet that the company will be watching what features are added next. I think they will continue to add new features and new functionality. For example, something that i don't expect might be a strong word, but seriously, wouldn't be surprised if it happened,. adding other kinds of ina insight aps like that, i think would not be a shock at all. Just opening up an api would be in yury of starting to see some extensions for fogogl crome that are specificlly designed for Google Plus.
