You shouldn't start using something just because others do. NoSQL databases are tools, and it makes sense to employ them when they actually are the right tool for the job. Does MySQL and relational databases in general satisfy your requirements for a given project? If yes, you don't need NoSQL. Some projects will require NoSQL. Others will require both NoSQL and relational databases (a great combo). It's all about what problem you are trying to solve.
