I would also like to bring up another point no here is mentioning - is that 90% of the original authors' books here are free, and I have read a lot of them, some are brilliant, while others are well ... not.
And one thing I have to mention is that so many of the novels here are original, while one can complain about the grammar and spelling mistakes, the plot itself is brilliant. There are so many hidden gems on WN that you could spend weeks reading and not paying one SS.
Look, not to brag or toot my own horn, my novel is already sitting at over 118k words, and I think by the time I have finished I will be at 2 maybe 3 million words. Firstly if I went the self-publishing route, it would take me a year or two to finish before I could publish on Amazon. Secondly, I would end up having to cut 80% of my scenes.
As with regards to translators - that is also a mixed bag, but no matter how much a translator messes up - it is still better than MTL the novel, believe me, I have read dozens of MTL novels, and besides the immense headache you get, your own English goes south for about a week thereafter, and you do get incredible translators like EndlessFantasy Translation, who I have to take my hat off too, their translations are one of the best I have ever come across.
What I do find unfair is how WN promotes so many books on the homepage, that are either horrible or haven't been updated in months, and half the time it is the same book over and over again.
No one is forcing anyone to buy SS, you can always cut back on your premium novels, and spend some time looking for those hidden gems. An example, Indigo Emperor by holachica, the novel is only 7 chapters, but the writing is superb.
A blog started by Book_Keeper https://virtualbookshelf.home.blog has started a good ranking system and reviews some of the original novels here - check it out if you are looking for something to read.
At the end of the day, no one is forced to pay for SS. WN has given their customers multiple options to gain access to premium chapters. And users of WN are given the unique opportunity to find budding authors, some who I do believe will go on to become published authors one day, and in the future, as a WN client, you were there when they just started out.
PS: Just my opinion but I do think that the monthly subscription is a bit too expensive. I think it would sell better, and eliminate many of the complaints, if they dropped the price to $10 to $15.
