set.seed(x) - does the value of x matter?

I know what set.seed() does and I am aware that each value produces an unique and reproducible random process. My question is wether it matters what value I use inside of set.seed(). I am asking because sometimes I see weird numbers inside of set.seed(), like set.seed(7*11*13). This looks like there is some idea behind it. So is this useful for some reason?
