1. A platform where it turns your individual posts you upload into a story of your life. All other platforms focus on individual posts that aren't connected and don't keep in mind what you want your legacy to be. This connects your posts and turns it into a story of your life.
2/3 I'm assuming you are using mobile to view the platform, mobile hasn't been completed which is the cause of the slow rendering and the ugly look of the platform while on mobile
What makes you think most people want such a thing?
And for those that do, why is Facebook or Instagram or a custom blog inadequate?
Facebook changed "wall" to "timeline" many years ago and has had a similar time-based structure since then. They even encouraged people to add major life events that happened before Facebook existed at all.
Simple - I had this built for myself. When I reached out to random people discussing the platform before I had it built, they loved the concept behind leaving a legacy. Pay attention to how many times professional athletes, movie stars, business people and the average person mention the word "legacy", wanting their life to have meaning and to leave a legacy after they're gone.
None of the other major platforms inspire to leave a legacy. Your point is valid, it's a platform where users can upload videos, photos, text etc like the rest of them. But each platform has a different circumstance, vibe or idea - linkedin is for business, employment ; snapchat is quick and easy highlight of what you're doing; facebook is the Swiss army knife based around your friends; instagram is simply photos and videos; but none effectively tell a story of one's life and inspire what you want your legacy to be, what you are about etc. They are all quick, one off posts that don't effectively tell a story of your life, which is what I think people are really doing when they are uploading content --> uploading a piece of their life's story bit by bit
