Twitter is a useful tool, but it isn’t always a good thing. If you’re using it to talk about your personal life and about how you just lost your job then that’s completely fine when you’re at home. But if you’re a school then that isn’t proper. In my opinion Twitter is a great tool for schools to use, but it must be used correctly or else there could be a problem. It can be a great way to share your projects with the world. In any case I definitely think that it’s a great idea for a school to use.
