How many spelling or grammar errors did you find in the last book you read? Was it an ebook or a traditional book? How do these errors color your overall feeling about a story?
I try to look past the errors to the story itself but sometimes there are so many errors that the story gets lost. I feel like a grammar geek, seeing all these errors out there. Finding all those errors doesn't have to be expensive - have a friend or family member read through your story. I found a couple of people through Facebook to read through my book and they found quite a few errors that I missed. I am too close to my writing to edit it effectively, but I can spot errors in other author's books with no problem.
I even found a Facebook page for a free editing service. Unfortunately, that didn't work out so well, the service has been temporarily discontinued. There was a complete lack of professionalism, I found out the service was being discontinued from a post on their page but they indicated they would complete any projects already in process. In my opinion they should have notified their "customers" personally (through email or pm). I have sent emails but have received no replies and the promised completion date is long past). I guess you get what you pay for.
What is your editing story? Did you have a good experience or a bad experience?
