For me if the people that love my stories want more, then I will give them more. I never want to leave my readers hanging. I know how it feels, and it is frustrating and horrible. You read this amazing story that really excites you and you find amazing. But then the disappear. Now if they forgot their password then I understand. I could not find my password,I tried to reset it,and never got the rest email so i had to start over. I also know that life happens. But...I think it's unfair to get a fan base,of people that truly love your work and never even give a heads up you just leave.
So in closing,I would not mind writing long term stories. I just have a bit of trouble stretching it out. I want to make it good for my readers.
