OP, this is definitely one of the - if not the most challenging corals out there.
There are quite a few threads on RC of success stories, here is a recent one:

The difficulty is trying to find foods that the Bluberry gorg will respond to. You definitely have to target feed it. There just isn't all that much scientific data and most of the information is from empirical reports from people who have had success.
I have one and it was doing great in the display but its not particularly happy now in the new gorg tank - it hardly opens up anymore. The main display was 77F and was very well lit - the current environment is kept at 72F and has much more subdued lighting - go figure.
