Startup Idea #39: Microfunding for creatives

Kiva + sellaband + viral credit chains = new financing model for media creatives that is both social and viral.

Media financing has been stagnated for a while. Helping artists to connect with capital suppliers is going to bring huge benefits to the industry.

Startup Idea #38: Social graphs as trust networks

Leverage on social graph to build trust and use that in turn to drive many other applications.

See originator of this idea here and here

Facebook is not a real social graph. Xobni is one such graph. So the opportunities are:

i) Build social graphs for social networks, blogs, microblogs, mobile
ii) A middleware to mash these networks into existing applications
iii) Build applications that incorporate the social networks

As mentioned by Matt, this is a multi-billion dollar industry
