Honestly, I'm perfectly happy with whatever makes the pnm comfortable. I am impressed with the tact that the pnms who have used proper names have used when posting, they have all been extremely lovely and careful. However, if they feel funny even saying "I really didn't click at ADPi" because they know that women on their campus read GC posts, then I support their decision to keep the chapter names secret. The pnms are the ones who have to go to school and interact with these women for the next four years. (And they have no idea how the actives at their college or university might recact to seeing that, "ADPi was nice but we had nothing in common." That actually could be hurtful to a new sister recruiting for the first time.-You really never know.)
I see the point about it being very helpful to the chapters, it provides them with a pnms view of their recruitment (as a rush advisor that would be a dream tool to have), it is a nice benefit but again, only if the pnm is comfortable providing this "help". I think pnms post here to get support and advice which they get a lot of, and in return I get a lot of pleasure out of hearing even the vaguest of details. But that's just me.
Basically I have become a full-fledged addict of these threads and like I said before, will take them anyway I get them!
