Top 20 is a lot easier than it used to be... :)
Depends what time of day we post these things. Morning DUFUs tend to get the replies faster. Evening DUFUs don't usually start out as fast.
Also, lately PJ and I have not been posting as many DUFUs as we used to. I just checked, and in the past 40 days, I've now posted six DUFUs, but PJ has posted only three!
Since Obamacare passed, the politics has been in a bit of a lull, and so have the DUFUs!
