How soon after a story has been posted can it be posted again?
Around here? About 20 seconds!
Check the "DejaVu" clock
We have "GUIDELINES". About 4 hours. But a lot depends on the topic. Is it hot, is it in breaking news? How many other posts have been posted? Is it so hot, we've been pulling tons of additional threads? If you post the exact same article 7 hours later, but it's number two in the breaking news sidebar, should we pull it? We discuss this behind the scenes. And sorry to say, a lot 'depends' on the situation. Case by case.
If it's just a generic repost, then we follow the four hour guideline. If it's a hot, everyone is following it, it depends. Moderating doesn't have the 'if then else' rules. It's a dynamic situation. Mostly we have a set of rules......Mostly, we can't follow them.
Jim always has the final say.
