The Economist has a brief article up about some high bloggers that have quit their day jobs to turn pro. Before you join them consider that there is simply not enough advertising revenue to go around. There are lots of people - including start-ups - that covet the same pie.
Can you make a good side living? Heck yea. But the folks who make six figs from blogging as their sole source of income will be few and far between. This will especially become apparent when there is an advertising slowdown - and there will be.
The pro bloggers that are doing this now, like Om Malik and Michael Arrington to name two, should diversify their revenue streams. This will include courting larger, more stable advertisers. But it goes further. They have a lot of knowledge and should begin to sell premium research reports on the industries they track.
