oyo.cash was build in just few days by a single person with basic JS knowledge. When people wake up to what bitdb is capable of, the BCH ecosystem will explode.
What else is BitDB capable of? Oyo isn't a Google-killer but it's definitely neat.
Its a simple way to interact with the op_return data without having to reinvent the wheel like memo and blockpress had to when they made their platforms.
It's just a easier way for developers to build on BCH without knowing everything about Bitcoin. That way we can make amazing platforms for you guys w/o reinventing the wheel ;)
