Ask HN: My app is live, should i register a company?

i have completed the first version my app (on the app store), this is a side project for me, and registered under myself. should i register a company, my reasons for incorporating would be to absolve personal financial liability and i do plan on charging money for the service so from a tax persepctive, separating the company taxes from my personal taxes, right now the app is free. anyone have experience on this, or can recommend a good lawyer with this type of background in the states? i am thinking particularly of a c corp in deleware. regarding equity, i had some folks helping me on the project, but i don't think they deserve any equity, but i've heard that single founder companies are not that desirable, funding is something i'm seriously considering, but the project is too early phase and i am doing most of the development and soon to be marketing myself. thanks in advance
