It is for you to find. At this moment it seems people actually found new Barnacles, but it is hit by some bug. It will get fixed and it will be fine.
edit: and beta is there to test things, not give you tactical pre-knowledge how system will work in the game.
Sure: in a galaxy of 400 bilions world without no clue (didn't take part to Barnacle's Cg'goal)
Anyway, let's see how they fix them.
In the meanwhile, ESO is a good alternative to Ed: at least, in that game, I always know what to do and where to go...
