That's fair enough, I dont' think this is on the devs. At least not entirely, but I'd argue that a company that can't maintain budget and scope & is off by _that_ much on the first estimate is not very effective either & should be 'fired' as a company.

And then there is the sunk costs which are not so easily dimissible...

That being said, it is a nice and fresh website. And congratz on the success with the product! It's something I've been 'dreaming' of, find a nice niche product and make it well. No BS.
