For people who wan't log on-have you tried switching your browser? I had the same problem on google chrome but I switched to explorer and I could log on no problem. Also you guys should be keeping most of your money in a encrypted software wallet I would never trust my btc to a exchange site.
I'm not sure but I think eventually cryptocurrency will leave the beta stage once new exchange rates that aren't incompetent such as mt-gox start up, they probably will stabilize and become a accepted mainstream on the internet. I'm in this for the long run, I will buy a few btc and forget about them for months.
