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.
Right. But what day-to-day usecases will The Average Joe have with such a database? What is its potential for BCH adoption?
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 ;)
