Yeah.  I'd say price stability is better that constant fluctuations up and down.  How can someone really invest in the economy if the exchange is always in flux.  The rising price is good in the short term but increases the likely-hood of a big sell off and price drop in the future.  That said, I would agree with shockD, Mt.Gox AML/KYC issues and also could be from lag in people pulling assets from Bitcoinica and moving them to other exchanges.
