I cannot dictate how my readers on my stories comment. Yes, sometimes I'd like more than just an "update soon" or "sequel please", but I think it's enough that they took the time to leave that much and want more from me.

When they don't comment. I mean, at least an update soon would be nice but no! I spent hours writing up a long chapter and I don't get any comments at all. And honestly, i think I'm at least a decent writer. /le sigh
It makes me lose inspiration to update, although I've written that for myself, I feel like no one appreciates my works.

Readers shouldn't become grammar nazis. I mean, they can correct a thing or two, but please DO NOT become my English teacher. Also, I hate it when they call me "author-nim". I have a username for a reason, you know.

When they correct the spelling and grammar . The author is a human too .

-'update soon!'
-'author-nim!'

On another hand, I don't mind if they mention something about grammar or a weird sentence. It's kinda embarrassing already if you didn't catch it. Unless the author did it purposely for their style/to indicate something.

When they correct the spelling grammar or they write how the author should have wrote -.-

When someone comment/bash other story for plagiarizing..
They should really read both story first, then they can judge..

i rather they comment about the chapter

just comment an 'update soon :D' as it kinda means 'YOUR HOMEWORK DUE DATE IS UP'
