As described, I love the targeted ad model, particularly if hubski can remember my interests and preferences for me, so I can mine my own data for myself. I'd like the ability to make it a push platform, rather than passive monitoring. I'd like it to be a two-way communication, in an explicit intentional way. It would be nice to work this in seamlessly. Reddit has sort have but not really done this, Yelp is a recommendation service with a social aspect. Well, given their extortionate business model, it's sort of an antisocial thing. But we are a society of consumers - of necessity - and we all love to talk about the things we like to consume, read and watch. I think it would be a mistake to turn that into hubski's mission - but as an adjunct to something that should happen anyway - solid, in depth conversations about those particular things, things the creators and marketers really should be here talking about themselves - I think it should be possible to monetize/recognize/valuate. I can't think of any example of this being done; not in any way that works. That may be that it's difficult, but I wonder if it's just that marketers are so used to talking at us, without considering any feedback other than sales. That, and the numbers themselves would be interesting. I'd love to see an open-source repository of those sorts of numbers and discussion of what they mean. That would be worth considering a tradeoff of privacy. I think the PBS model is interesting as a means by which people could contribute to the site. There are any numbers of ways this could be done - but let's say for example I find an interesting thing, make a cool thing or draw a wonderful picture. Perhaps I could put it up for auction to benefit the site. This might be a better way for low-income persons to contribute, but there's also more sense of participation and contribution.
