For the friendship app and website, I would like you to conduct market research for me. This is a universal business concept that has to be covered.
This business is good. One should do this business. There is a long future for this kind of app/site. Will more people join? Will it be a good business in the future? If so, why? Who are the rivals? What strong features must we have to make us better? Does this concept have any future suggestions?
