So far I've tried promoting Blockbuster Online and a couple of other popular programs. No impressive conversions. I guess it's because most people have already heard of those services and won't signup because of impulse. Are there any niches out there that people really don't think about that are pretty good?
That's a very good question but I don't think you'll get an answer here. Anyone who has thought of a potential niche market, and then done all kinds of research to determine its viability, isn't going to share that information with anyone.
