Lately I have been having a harder time getting HITs completed in a timely fashion. I can tell that HITs are getting accepted but not actually worked on. My assumption is that workers are using scripts to automatically accept a HIT but then the worker is not available to actually complete the HIT. While the HIT is sitting in this queue, no one else has the opportunity to work on it until it expires and is made available to another user. This appears to repeat several times before the HIT gets accepted by a worker who is actually going to work on the HIT. Here's what I'm thinking of doing to address this problem. Instead of having a HIT that says a worker has an hour or more to submit it, I will create my HITs to only give users about five minutes to submit the HIT. Now, I know that some of my HITs can take longer than five minutes to complete. For example, if the HIT asks you to review a site for 20 minutes, there is no way that you can finish that task in five minutes. Instead I will be asking you to accept and review my HITs and then submit them before actually doing the associated work. As long as you upload your video in a timely fashion everything should turn out fine. Please let me know how you'd feel about such a change.
