Creating a new social network is like launching a rocket into space, it's a very complex project that requires a team of professionals, and if you don't even have experience with programming, how are you going to manage your hypothetical product? It's good to have ambitions, but if you have such a giant goals, you have to either become realistic and give them up, or devote your whole life to achieving them.
Programming knowledge doesm't matter here, it's more like marketing because nowdays it's pretty easy to create facebook like website, even that would be very shit because you need your own CMS (if we talk about project that wants to achieve anything good in future), huge work on security, a team of professionals and etc. You have to control every content, scan uploaded videos with their id to get rid of copyright issues and so on, this is just basic of what facebook has and this requires huge resources which costs millions + need a team of professionals but still, If you want to achieve something, it's almost impossible on global market because of natural monopoly. Facebook/twitter are most widely used, everything has it's time, it would be easier 10 years ago but now? Still don't understand what do these people think when they have such ambitions. Be crazy in your dreams, that's great but at least be a little realistic, there are dreams which will stay dreams forever. Don't wanted to repost here again but can't understand why realizing of all above things seem so difficult for people.
