I couldn't agree with you more. When you are a member of the HN community, there are likely many things you take for common knowledge. I think it is useful to take a step back sometimes and just remember how technologically simpleminded a lot of people are. This often opens your eyes to opportunities for new products and services that wouldn't make sense to a programmer. Other times it is just the opposite, however, and the HN community will be able to provide you with the best feedback for certain types of products.

The key takeaway here is know your user.
