....I'm not sure enough people want to preserve their online lives to make a viable business model...
But doesn't it start with 'throwing in your line'? I'm not clued into social media but, from what I've read and heard, if I wanted lots of common interest input I'd get with the program.
As I recall, in brainstorming sessions the first rule is just to toss the idea out there and see what the group does with it.
You're plugged in to the social media so you have a way of floating your idea, however you decide to massage it, over a very wide area if only just see what happens. You may be surprised at a) the number of people who do have an interest and b) the ideas they have for making a good business model.
