I find it interesting that you talked about nutrition supplements for athletes. I am very close to launching such a product for enhancing aerobic exercise performance in women (ie. improved times in a 3 mile run).. The product contains no stimulants or exotic herbs. In fact three of the five ingredients are well known minerals, but in forms not found in most multi-vitamin-mineral supplements. The research behind the product comes from me. The credibility behind the research is that I am a professor of human nutrition with over 100 research papers. Now, the trick will be to use my connections and credibility in a business savvy way.
You have also mentioned Quuu for article sharing and driving traffic. I have been using Quuu for quite sometime now and I don’t think they’re worth it. While the content does get shared a lot, there are hardly any clicks to the site. Even the clicks that are there, average time is like 0.02 seconds compared to more than 2 minutes for other sources of traffic on my website. I have heard a few guys having a similar experience with Quuu and so, I thought should let you know.
