I suspect that this is the point - FD got burnt with the original site when some clever person (people?) figured out the location from the sky in video/images and the site was found faster than they were expecting - before they were ready from what I've read. I think they have deliberately made this next site very difficult to find with absolutely no information to narrow down the search. Maybe someone will get lucky, but if not, I suspect Ram Tah will make additional discoveries in the next few days/weeks, on a timescale of FD's choosing.
FWIW, I don't believe that there is any information hidden in the arrangement of the first site for 4 reasons - 1) AFAIK, all the information derived from the site has come from data scanned from the objects, not the arrangement of the site, 2) having the solution in plain sight (or site, ha ha) runs the risk of the very first person looking at the site (if they are clever enough) solving the problem immediately, 3) it would seem odd for an advanced space-faring race to encode information in such a prehistoric fashion, particularly given that information is also encoded electronically, and 4) when FD decided that we needed/they were ready to give us more clues, these clues apparently came from the data, not the structure of the site - Ram Tah could have announced that he had discovered, for example, "that the positions of this or that part of the structure makes a star map" or "this section of the site seems to be a message which I have partially decode in this way", rather than "look what I've found in the data"
I don't think people should stop trying to decode the first site, but it wouldn't surprise me if we eventually discover that we have been trying to find meaning where there was none ... much like life
