If I was pg my first question to the Crowdbooster guys would have been "What happens if twitter builds this?". And if I was the Crowdbooster guys my answer would have been "Could twitter do this?" and shown plans to integrate with a gambit of other platforms creating a central SNS hub with Twitter as just the beginning. When building on a platform you should always have plans for what happens if the platform (or someone else for that matter) creates a offering similar to your own.
