What is your “this-should-be-just-blogpost-not-a-book ”?

I mean so many bad books being written left right centre by wannabe "best selling" author. I am going to exclude being harsh on technical books - I can't judge because I don't know everything. Also nothing against fiction book. But for God's sake, what is up with self-help, motivation, life advice etc. Honestly, they have a drop of milk and then they add 10-litre water and they proud of being "bestselling author"? I am not blaming everyone but you understand what I mean.

I think if you don't have solid 10 different ideas then there is no point in writing a book. Some bloggers have more content on their site then these "authors" with 10 books combined. Needless to say, I am throwing more books faster than reading them.

Do you feel this frustration too? Do you know any book which should not have been a book? Can you tell us why you think?

I hope this list will help us not to waste our valuable time reading worthless book also save us some money. Thanks :)
