I have always loved to create a site that would assist little creators in being recognized. I already created a forum around that. There are so many great individuals who remain unknown just because they are not exposed. I would turn it into a place where creativity is literally appreciated, and not pushed by algorithms. It's here
I'd probably create something similar to Beam/Mixer and offer an alternative to Twitch. A platform ran better and without the drama, toxicity and BS that Twitch allows on it's platform.
I had created so many websites in the past, and none of the websites became popular, and I am also a failure. I cannot dream anymore about making websites in the future,as it needs a huge amount of work and money too.
I'm currently in the middle of creating a marketplace for anyone, but the focus is where site owners, creators, and developers team up to exchange ads, content, skills, and opportunities - or just plain simple buy and sell digital assets. It has a providers directory where you can offer your services, it has listings where you can offer whatever you wish to trade, sell or buy. It has a wishlist system in place, it has private messages, etc. I'm still creating more features to make it a fully featured marketplace.
Other than that, I have many more ideas to build things, but time is my biggest enemy.
I would love to create a forum where teachers can discuss and share their experiences. There are a few of them around, but I would love to own one as well. This will be an avenue to get teachers to talk about what we do, and we all appreciate it.
