Friend Codes: Yay or Nay?

Okay, let's try to do this right this time.

For wireless networks there are different ways to connect. Microsoft has XBox Live, PC games vary from one to another,...and Nintendo has Friend Codes. Yes, the multi-digit numbers that you have to enter for every friend you have. On the one hand, it allows for direct connections without having to worry about sifting through thousands/millions of other users. On the other hand, you have to enter one for each friend and most games have a limit on how many you can enter.

So, do you think they are a good idea or a bad idea, and why? Is there a different kind of system you would rather have?


(yeah, I'm taking the idea from someone else, but that thread didn't work out so well for obvious reasons, so...)

NAY
Just have a search function, and the ability to deny and accept friend requests, if you don't know them, just deny it, if you do, accept it.

If the wii had one code, I'd be fine with it, but it has multiple ones, if it was the system code for everything It would be fine
