Appreciated post and welcome. I tend to agree with most that you said. In particular we have to be careful with TA and BTC, in can turn on a dime for no reason.
Can't comment on Jaroslaw. I have never ignored a poster as I think there is occasionally truth in the false, so I don't like to filter information. Though, at times, it certainly gets tough ;-)
I'm guessing it's because most traders (including well backed ones) are spooked by the fact that this is entirely unregulated. If Mt.Gox gets taken down, who do they raise a law suit against to try to get their cash back? This prevents most traditional traders from getting into it.
I considered it to be a HUGE risk to deposit c.£30k (c. USD$50k) into a Japanese bank account with zero chance of recourse should they decide to make a run for it or be brought down by the Feds.
I decided to grow some balls and go for it. Either I have bigger balls than most traditional traders or I'm more reckless. Time will tell, I suppose....
EDIT - sorry, that was meant to be a response to "stereotype". Spot the newb forum user!
