Well I think from 2000-2010 it was all about webcomics. It's easy, most of the time free and you get a lot of people reading your stuff. But it was hard to make money from it. It was the alternative though compared to trying to get accepted by a publisher or dumping thousands of dollars into self print and trying to distribute it yourself.
But just as the indie boom of the 90s differed from the 80s, and the 00s differed from the 90s, the 10s is entering a new era of pay before you get, with many fund raising sites that allow people to raise money for a project as well as getting sales before it's even done. Web comics will still be a place for kids and amateurs but you gotta ride the tide.
