I'm not as eloquent as others out here, but here are mine.
Short and sweet (or not).
The so called 'author' is asking for MONEY.
EXPECTS people to pay MONEY for the words they put out.
The reviewer isn't asking for MONEY when they write their review.
This one always pisses me off.
Opinions are like assholes.
Everyone has one.
Get over it.
Said reviewer writes the review for other readers, not the author.
Yeah. Other readers might not want to read about that.
Well, write something new and original?
Then your book won't be confused with someone elses.
If a book is crap, is doesn't take the whole book to discover that.
See G2 and B4.
