I went out to the rift area some months ago and did some exploring but other than some interesting systems I didn't come across anything interesting. It might be that there was nothing there at the time to find of course.
I crossed using the Heisenberg bridge
and there were a couple of occasions where I had run out of FD boosts and was stuck looking on local planets for synthesis ingredients. If you go, make sure you have a good jump range on your ship.
I was tempted to go back as things appear to be moving now.
