As cliché as it sounds, make the content that you want to make. Unless you are trying to make a career out of it, don't try to pander. Don't expect anything either.
And just because someone has already covered something, doesn't mean you cannot add to the conversation. Try to add a unique perspective on it, cover it in a different manner, maybe play devil's advocate and make a counter to it even if you ultimately agree with it. I get where you are coming from, I don't like talking about things I feel like have already been covered extensively but there's nothing wrong with getting inspiration.
It doesn't have to be perfect, it doesn't have to be unique, it just has to be yours. The hardest part is starting. Make a list of things you may want to do and pull one out of a hat or something and just make it. Have a (realistic) deadline.
Don't think it's good enough? Could be right. But it's the internet, the biggest trash heap on information in history. No-one really cares. Have fun with it.
