Thankfully they have ignored your for-the-5th-time question and the funds are now safe at mtgox.
I think they would be a lot safer if they were held in an offline wallet, or converted to a fiat currency and deposited with an institution with insured deposits.
Is there any reason to believe that Mt Gox isn't today exactly what/where Bitcoinica was 6 months ago?
you got it wrong
Bitcoinica is nowhere near where Mtgox was a year ago and never was
That's great news! Perhaps you could explain what facts lead you to that conclusion, so the rest of us could feel as confident.
Mtgox survived one or two hacks last summer, they've upped their security probably withstanding more attempts since then than any other bitcoin online business. They're DDOS resistant to capacity that technology allows. They've had backups and were able to rollback their books after last summer's hack. And they were one of the first using cold storage for majority of bitcoins on their exchange. I'd say out of amateur company last year they've grew into one of most if not the most technologically solid bitcoin companies today. Other than deposit/withdraw issues mainly due to interfacing with fiat-ruled world they've upheld their reputation as an exchange on high level.
Bitcoinica on another hand? I've lost count how many times it's been successfully hacked into and stolen from, there were so much fail, negligence, hindsight to security that it is not even comparable with Mtgox. Apples and oranges.
