What is a blog. Questions

A. According to this author where does the word blog come from?
A blog comes from the word "weblog". Then in 1999 Peter Merholz, an author decided to change it from web log to we blog. And since then a blog existed.
B. Why might the writer object to a book about blogs? What is the difference between a blog and a book?
She might object because it might be hard to put blogs on a book. There is a difference between book and blog because a book is not as reckless, or as fast as a blog. In a blog you can write freely and its faster to do so. It might call your attention more because of all the different topics it invites you with and is not as closed as a book. Plus you can comment or decide what to read and what to skip, when in a book that’s impossible, because if you do you will just get confused.
C. How have blogs changes recently?
Blogs have changed recently because now days you can find a blog about anything, and not only one, but many on the same topic. We could say they have developed.
D. Why might you read a blog rather than a book, or a magazine, or a newspaper?
In a blog you can find a lot of information about the exact topic you are looking for. There you can also comment and decide what part you specifically want to read or which one you prefer to skip.
D. Is there reason to doubt the objectivity of a blog? Why? Why not?
I don’t think there really is a reason to doubt the objective of a blog, because at the end they all have the same objective which is to inform or help the people find what they were looking for. Even though different blogs will have different specific objectives depending on the topic they are based on, they really all have the same general objective.
E. If you kept your own blog, what would you title it?
Everything and Nothing at the Same Time.
F. Find three blogs that mention our summer reading.
