First I've heard of it. Might have helped to not just listen, but to actively advertise the beta via a link on the main website. Pretty standard practice.
Yeah - but how does a site which was initially projected to cost $4M AUD get to $96M! A 16x increase! The mind boggles.
It's pretty nuts. I want to know where that money went. Something like this needs a full post-mortem, or a Royal Commission as they call it
