How long would you say it takes before you decide an Internet project is officially dead? Two months? Four months? One year?
I read stories on Fanfiction.net sometimes. Every now and then, I come across a very popular, very good story. And then, after I'm five chapters in and I'm completely hooked on the story, I notice that it's unfinished, and it hasn't been updated since 2003.
Well, if the author hasn't written a new chapter in nine years, it's a pretty good bet the story will never be finished. But sometimes, the author hasn't written a new chapter in four months. That could mean the story has been abandoned, or the author has just been too busy to write much lately. Where do you draw the line? How do you make that judgment call between "the project is dead" and "the project has been delayed for a long time"?
Personally, I decided to make a special folder for projects I like, which haven't been updated in a while. Every six months or so, I go through the folder to see if any of them have been finished. Sometimes they do get finished, which is always a nice surprise.
