Ok,
I am willing to point out typos, in hopes the author will take it graciously. But if after a few chapters and nothing is edited, I will stop doing so with that author. If the errors are to many for my immersion into their story, I will drop the story.
I always thank my readers, but I do editing in batches. That's also usually applied to the master copy document first and very slowly rolled out to sites like this. When you cross-post to twelve sites and have hundreds of chapters for a single book it can be a massive undertaking to update everything. I also have a backlog of 50+ chapters for all my books, so it's not like I can just learn I'm missing a word like weary vs wary and suddenly have it fixed in all future chapters either.
I don't think you're even one of my readers, but I thought I'd share my own methodology as other authors might have the same issue. Just because it isn't immediately fixed doesn't mean the help isn't appreciated. Just means it may take a while to see the improvements.
I changed a characters name on accident and noone noticed. It happened like 5 chapters ago.
Sometimes it takes thousands of readers to see the same mistake just to have it pointed out once. I get certain names confused all the time. Either I'll mix up MCs from two different series of mine or it'll be something about a specific name my brain doesn't like. For example Veronica vs Victoria, Alaric vs Aldric, or even Kenric vs Kendric. All real examples of names I've messed up in my work that had to be fixed in editing after learning they were messed up. Luckily if you compile all your chapters in the same document you can use the find and replace feature to change it all to one version.
This mostly the same for me. Sometimes I'll go to point out a typo, only to see that someone has already pointed it out in the comments. But if someone else pointed it out and the chapter hasn't had the typo fixed what is the use in doing it again?
On RR I have a story that thousands of people read. I end up with half a dozen comments pointing out the same error. However, I cross-post to twelve sites so what might take you 30 seconds to point out could take me 15 minutes to fix. I'd have to identify where the error is, fix it on the master copy, and then recopy and paste all of the formatting onto all of the sites I just posted to. Even if it only took a minute per site to format things, it adds up.
As I said above, my methodology is to thank every commentor for their help. Then once a month or so I will go into the mastercopy and make all the edits everyone has suggested for all of the chapters, try and run Grammarly on it again and have it struggle due to the massive size, try and run the document's grammar and spelling checker again and have it barely point out anything, and fix anything I personally notice along the way. Then I'll spend like 5 hours per site per book posting the edited version with its formatting because all of my newer work is more than 100 chapters long. This of course means it can take weeks just to update every site one time since I also have to write and do normal life things.
So, it takes forever to see the changes you want fixed, but it doesn't mean that the help is being ignored. I'm sure others could have similar problems that get in the way. However, you also have to consider this is a free site with a lot of hobbyist writers, you aren't going to get professional quality.
