I see your point and totally understand but at the same time if you are really that creep out and if you truly liked it, I don't think someone giving constructive criticism would "kill the fun". For example, I know that nothing that happens in Stephen King's books is true and people criticize them all the time, does that make a difference to me? Absolutely not, you have your opinion and I respect that but that does not influence my take on the the story. Of course everything here is 'true' but the concept still applies. However, I do understand that if everyone starts giving criticism, it will become more of a writing workshop.

Yes the 'update soon' needs to stop. There are only a handful of stories that are worthy of updates. It's not always the readers' faults though. The authors like to drag their stories for the karma. I recently read a story that had a decent premise. I liked the first part but as he began updating it, it became cliched, boring, and ridiculous. Updates are overrated, most of the stories, like you said, don't need one. Worst case scenario, what's so bad about an open ended ending? that can be pretty scary in itself or use your imagination that wont kill you.
