My thoughts are a bit different on this subject, but I like where you're coming from and can definitely see why it would be a nice thing to tell who exactly it is that nuzzles you. I've been there before where I've noticed a nuzzle and it does make me want to thank whomever gave it, even if it's a very small (but sweet) gesture, however...
I think what makes the Nuzzle/Floof-O-Meter so interesting is that we don't know who gave the floof-- and I think it makes it exciting, to say the least, having no idea who gave you a nuzzle. While this contradicts your point a bit, I think that the very concept that we cannot be certain of whom gave the nuzzle is exactly what makes it so interesting and still a fun option to be implemented into the forum. There have been times when I have given a nuzzle and did not necessarily wish for that person to know that it was me who nuzzled them-- simply knowing that at some point they might see the little number rise by one number was good enough. I think, in a way, I would rather not know who nuzzled me and rather have either a bit of guesswork on my own part or simply not have to think too hard about it.
If we knew who nuzzled us, I feel like this may be abused in some way, although not in the way that you may think. By being "abused," I mean that some users may feel like nuzzling a specific user in knowledge that they (the person who was nuzzled) may notice them and give them attention for the sake of being noticed. There may also be the case that some users may feel the need to nuzzle a user back if they were nuzzled, and then, it becomes more of a "Nuzzle me! I'll nuzzle you back," or "Thanks for the nuzzle!... Does that mean I have to nuzzle back as a thank you? Will they think that I'm not nice if I don't nuzzle back?" and it loses the whole point of the nuzzle system and could become an entirely new thing. It then becomes more of a necessary and something that one may feel obligated to give rather than by one's own true intention (that is, they shouldn't feel like they have to give one in return if they don't feel like congratulating somone with a nuzzle). On numerous other websites, such as Tumblr and Instagram, any sort of "like" feature can fall victim to this, and I think it could easily be abused in a very similar way, even though it's not malicious. Truthfully, I feel like it loses its charm as soon as it becomes a system of exchanging graditude rather than simply giving a small pat of appreciation to someone. I think the anonymity is what makes it special and fun.
Anyways, these are just my thoughts on this, although I have to agree that there have been times when I too have personally been a bit curious. I do like the idea of having a notification when your Floof-O-Meter goes up. I think that would be something interesting to add. Thank you for your suggestion!
