WordPress is an amazingly versatile putty in your hands publishing and content management solution for the Web. It's open source and free.
But, it still takes geeky programming skills, purchased or custom plug-ins, a targeted marketing strategy, relevant content, great design, significant offers, and a solid business model. The cool thing is that once the site's built, WordPress is a lot like graffiti. Anyone can stealth-post in the middle of the night and the update's there for everyone to see in the morning. It can be instantly gratifying to tweak, post, upload, and switch gears – on demand – when the market changes, prices should be slashed, news breaks, promotions are time sensitive, or you have to make some noise ASAP.
