Nah, that's a myth.
Slop and randomness do not make a groove.

Roger LInn recently said
"In my drum machines, I wrote the software in such a way that the  
notes play exactly at the correct timing location. And for the  
included drum sounds, I insured that the beginnings of the samples  
were closely trimmed to minimize any delay at the start. I’ve heard  
lots of theories over the years about other timing tricks, like  
introducing random timing variations into the notes of the beat, or  
delaying the snare on 2 and 4, but I’ve never found these to do much  
good. In fact, I’d suggest that if the note dynamics and swing are  
right, then the groove works best when the notes are played at exactly  
the perfect time slots."

And that is also backed up by the Innerclock experiments on their  
Litmus test page I mentioned.
