I believe we are reaching a point where the 15 min. fakers are being weeded out. These dot com folks, SEO cheaters and other class of folks have been put down by the big search engines and directory's technology. This presents an opportunity for real internet businesses to become visible and rise up out of a sea of get rich quick idiots. This growth, though small is adequate for ligit shops to move in and set up a long-term infrastructure condusive to substantial longevity and ROI.
Information sharing is an extremely profitable business - in fact, you can even solicit big companies to sponsor a blog or a useful website. Products are ok, but information is far more valuable long-term.
