Writing in the Modern Age

I think I've read over 2000 'normal books' over my life... but in the past few years I haven't read many 'normal books' from cover to cover anyway. The last time I bought a normal book was in 2008.

I really see the future of writing being in the internet more and more. The question for the modern writer is- how to make money from this? It's a difficult question, but one I'll aim to find the answer to, then write about!
