Book about the internet. Ideas for a topic please ?

I think you should do the first topic: how to be more productive online. It would take a lot longer and I think it would just make a better book. I think maybe in your book you could make a secure password chapter, because that is a good thing to write about, it would just be hard to make a whole book out of it. Hope this helps!!! Make sure you tell us the title so I can buy it when it gets published!!!!!
