Blog questions

1) A blog uses digital encriptions or in other words colored light to show what is written while a book uses ink and alot more natural resources than a blog.blog:uses electricitybook:trees and ink to be able to write
2)i have never used a blog before so i cannot tell you this truthfullybut i believe that they have changed alot
3)because it is easier to use than a book to use and alot faster ro read and correct through
4)i have no clue if i should doubt the blog maybe because the computer can fail but other than that i do not think there is any other reason to doubt a blog
5)probably whatever name came to me at the time but most probably it would be brownrev or wolfblade or some other fictional character that i have written about
