I have an idea for a web app that I want to build – a supplement search that allows to search every supplement on the market based on their active ingredients, allergens, price, etc. I figured out that I can aggregate most of the data, publish it as a spreadsheet, and try to promote it on Reddit and other social networks. My thinking is that people who are trying to find supplements and want to compare different supplements would use my web app to discover which supplements work the best for them. However, is there is a business in this?
How many directories do you frequent that you discovered via “promotion“ on Reddit and other social networks?<p>Do users of Reddit and other social networks enjoy being promoted to?
