I can't say I would absolutely need any of these things, but their uses seem like they would work well in special cases, like some with some big company or something. I suppose there is a market for these things, but overall I'm not sure how necessary they really are...I think I may just not be reading about them detailed enough, nor do I want to cut down on the hard work of these developers, but how necessary is the next step in social TV, or something..
