I know quite a bit about it, and I was just in a conversation with a domme on Loyal Fans who both does a lot of findom but also said she hates the word because of what it means now. I do think that the cam girls demanding tips or else they'll boot you out the room is kind of what a lot of people think of as findom today. There's obviously a more sophisticated version of it as well. But there are people who only do the cam thing. Check out the blog, yourmoneyslave.com, for example.
