"Producing investigative journalism on the web is not really hard (or any harder than it normally is) if you’re producing other content too i.e daily items about the latest news and trends. If your focus is purely investigations, you will struggle to build a web operation. The economics of blogging and online news publishing dictate that you must publish stories frequently. The average tech blog, for example, posts 10-20 short form articles a day. It’s how they increase their readership (and consequently, attract advertisers). But investigations can take weeks, months and years to complete. So unless you have a few hundred reporters working for you, you’ll never be able to post as much as TechCrunch. So you’ll struggle to build your audience and advertising base."
