This is hardly a new thing
I hope there is still room for good articles and the Gertsmann reality show on the interwebs.
I don't think writing like other creative endeavors is an profession as much as it is something some people can't help doing. Technology has made it much easier to share your work so the competition gets a lot tougher. I bet there are plenty of musicians who have written songs in a day that are wildly successful and then labor on some album for years that never finds any audience.
