I got a few reviews for my work Top 5 Mistakes Authors Make from some readers that had some more mistakes that authors make that can be very aggravating.

"I would like to add my two cents. Rushing, It is the most irritating for me
when an author rushes their story just to get to one particular scene that
they have plan."

Yeah, when authors rush, it can completely destroy a work of art. It's almost the equivalent of the Hindenburg on the "failure" scale.

Wheelwright says:

"Thank you, thank you, thank you!

May I add my own favourite mistake? Tenses! Why on earth do people forget
which tense they have chosen at the beginning of their story and jump from
tense to tense like a squirrel from branch to branch? There have been stories
with an intrigueing summary (And just why can't people spell the word
'summary'? I've stopped reading, simply because I was tensesick after the
first three or four sentences."

I don't know why I didn't think of this one for my list earlier myself. I have been baffled with the amount of authors that don't know how to use tenses.

"LOL I rofl at your example for mistake #1.

And here's something that turns me off from a story.

Endless AND unexplained hiatus
It really makes me wanna tear the writer apart limb by limb and shove them
into a pot of boiling oil if they suddenly stop updating for MONTHS and
doesn't leave an explanation AT ALL.
Especially when its from writers who post really really great work and know
they got fans dying to know what happens next."

I too have suffered from an author doing that I am reading around 5 or 6 stories that are never updated, but are excellent. If I receive more reviews about mistakes authors make that are all too true then I shall post them in another chapter. Also, Since I am a BETA reader, I will most likely only updates this in my spare time, because their projects shall take precedence over mine. Oh, and just for the record, I am reading roughly 27 stories right now. Any more and I would explode.
