I used to keep it nice and tidy, but recently, especially with some of the Tat's, I'll deliberately go for more to bring back that initial kick of pepper.
It can make the cigar harder to smoke because the end gets so saturated with saliva that the tobacco swells and the draw is compromised. At some level the end will get a bit saturated but once the head starts to lose shape because you have been chewing it like "chewing tobacco" you pretty much have lost the who idea of smoking a cigar.
