One point about the translation quality. Although I, as an English speaker since I was like 7, like to have good grammar in my books, I'm doubtful that most readers here have English as their first language (or learned it when they were young). English is the people's language in the sense that if you have a German and a Taiwanese guy in Italy that need to communicate, they're going to do it with some form of broken English, more often than not. I don't remember the exact statistics, but the amount of conversations in English that occur between 2 native speakers is staggering low, something like 1-2%. I guess the point that I'm trying to make is that although some readers are alienated by the bad grammar on certain books, the amount is probably much lower than you would think, considering there's a good chance that a lot of readers don't even pick up on the mistakes, or even care. I still think good grammar is important, but then again, there are countless books out there, and if people really dislike it, then the translator isn't going to get readers, hence no revenue, hence is going to stop. Clearly, this isn't happening, so the issue is not that big, although it is admittedly frustrating for those who grew up reading western novels in English.
One thing I think is bad for the community is free SS. Admittedly, if you can't read anything for free, readers would be angry, but I don't think free SS is the solution. People can just make multiple accounts or read off of third-party sites and not need to pay. Of course, removing free SS would not remove people reading for free, but it would make it harder to read for free, or more exactly, it would make it less obvious, meaning people would be more inclined to buy SS. Clearly, we can't just remove free SS and not give anything in return, because then you'll just have more angry readers. I think a decent solution would be to make it so that every time something like 3 premium chapters get released, each user gets their first locked chapter released.
Basically, if a book has 900 chapters, free readers get 1 chapter for each 3 premium chapters, so when the book is done being translated, 300 are free and 900 are locked. If a user buys 100 chapters, since the first locked chapter would be the first one released, then they would have 400/900. Doing it this way means a few things:
1) Free users still get a chapter every ~2 days (more than the current premium system)
2) More incentive to buy SS since getting free chapters becomes more tedious and annoying.
3) More incentive for users to buy SS, since after reading 1/3 of the way through over such a long period of time, you're probably going to want to keep going.
4) More incentive to buy SS due to the earliest locked chapter being unlocked. Back when premium started, it was a fixed chapter being unlocked for everyone regardless of if you've unlocked something or not before. Hence, if you bought SS then stopped, you lost your free chapters even though free users got theirs, which was really frustrating. With this system, if someone buys 50 chapters, then they're permanently ahead 50 chapters, regardless of if they keep paying, and are not locked into it to keep daily chapters.
Anyway it might not exactly be the best suggestion, but I do think it would be better than what they have now.
