There was an article about France's best known blogger, Loïc Le Meur, in the Financial Times. He has ten rules for achieving success in business. I found it quite interesting and copied it all here
1- Don’t wait for a revolutionary idea. It will never happen. Just focus on a simple, exciting, empty space and execute as fast as possible
2-Share your idea. The more you share, the more you get advice and the more you learn. Meet and talk to your competitors.
3-Build a community. Use blogging and social software to make sure people hear about you.
4- Listen to your community. Answer questions and build your product with their feedback.
5- Gather a great team. Select those with very different skills from you. Look for people who are better than you.
6- Be the first to recognise a problem. Everyone makes mistakes. Address the issue in public, learn about and correct it.
7- Don’t spend time on market research. Launch test versions as early as possible. Keep improving the product in the open.
8- Don’t obsess over spreadsheet business plans. They are not going to turn out as you predict, in any case.
9- Don’t plan a big marketing effort. It’s much more important and powerful that your community loves the product.
10- Don’t focus on getting rich. Focus on your users. Money is a consequence of success, not a goal.
