Huh. I thought this was something completely different. I thought this was a robot to help cross-references submissions about the same topic, and find duplicates that the built-in dup detector doesn't find. As such, I thought it would be valuable.
If it's a bot, I can see the value in it. It would be better as a built-in feature, but nevertheless it makes sense. I just hope that it doesn't inspire less useful accounts which would be more akin to Reddit's novelty accounts.
