My best friend has a ragdoll - he is very, very, very shy and will not come out at all if she has people over. He isn't a lap cat either - not very affectionate. Another friend has a ragdoll that can be very aggressive to cats and humans alike. My feeling (and my opinion only) is that with any breed you will find variances in general idiosyncracies, i.e., Siamese are often one-person cats but you'll find some that are very sociable with everyone, etc.
