Question
As per my research till now, there is no single platform till now which lists and allows to buy the latest technological products. If people want to know about products they have to follow some blogs regularly, and even blogs also won’t guide the people how to buy those products. There is no specific eCommerce platform to sell physical Technological/Innovative products.
Answer
Essentially you want to create a tech blog with more embedded purchasing options. Tech blogs work, so if done right there's no reason this idea would not work.
