That sounds like it will be a cool talk. I think Steemit can offer all sorts of oppunities. It initially looks like just a blogging platform, but it can also be used for commerce. People are already setting up services, e.g. video streaming, where they take a cut of any rewards. It's got a few issues with spam and abuse, but they are a risk when there is no central moderation. It's up to the community to deal with these. Stellabelle covers the main points.
I'm just a casual blogger who is having fun here, but I've managed to earn a nice bit of extra income.
