I hate that so much!!! Like, I just updated even though I was busy but you write, 'please update soon'?!!
It annoys me sooo much!! Those comments make me not update until months later.

I understand the update comment but don't think people should use just that as a comment. Sometime people are so excited that they cant wait to read more especially after a cliff hanger lol.
I always make sure to give a comment and I sometimes add can't wait till next chapter (at the end of a comment not just comment i want to read more and that's it) rather than please update because I've heard how much it irritates authors.

I get 'Omg love this, update author-nim' Come on I just did. I then feel rushed to do another chapter just to please people.
