When I see a story that interests me, I read the first chapter. If I feel it is my kind of story and it states "To be continued" I check the author's other posted stories. If I see a lot of stories with "Incomplete and Inactive", I will never go back to that story or author.
There are a lot of good stories that I keep track of and read but I just can't waste my time to get involved in a story and then be left hanging out to dry. So when I see a lot of that phrase "Incomplete and Inactive" in an author's catalog, if you will, I will just ignore him and move on.
In closing, if you are that kind of author, may be you should finish your stories before starting new ones.
There are a lot of good authors here and I enjoy reading there stories, even the series. Almost like going to the movies when I was young. "What will happen to our hero. Will he get out of danger before it's to late. Come back next weekend to see the never ending conclusion." I know, that was just a joke.
