Entrepreneuring on the web

Looking at articles in Business Week like this one covering Kevin Rose (Digg.com) makes me realize several things about being an entrepreneur on the web today:

• You either need to be able to do something yourself, or have the cash to actually hire someone who can. It sounds obvious, but you’d be surprised how easily you can talk yourself into “I’ll find someone who knows how to do this, and we’ll split the profits.”
• A great way to offer a successful service is to find out something that web users are doing already or want to be doing, and come up with a better way for them to do it. (In the case of Digg, that “something” was “find and share cool links with other people”).
• In the increasinly long-tail digital world, there’s as much money or more to be made in successfully aggregating  content (being a filter) as there is in creating it. Practically every link on Digg sends you to another site, and it’s almost as popular as the New York Times.
