They're planning on extracting social data from emails when most people use social networks for that task now? It seems they're asking that people 1) start using their system instead of facebook et al 2) change their email address (unless it works as a plugin on other clients). If they plan on option two then I think they'll encounter problems: most people I know only use outlook for work use and the web-based ones are unlikely to allow this plugin when they could implement something similar themselves (as gmail already seems to be doing...) Besides, if they do want to extract social data I'd guess they would need to structure their site like a social networking site which means it will merely become another social networking site. It seems a very good idea, except for privacy concerns, but I wonder where they'll obtain the users when everyone uses facebook et al for online socialising.
