There was a thread similar to this on world4ch /lounge/ a while back, but a lot of them were militantly against the idea of an ID, even after it was explained in detail of how it works. Considering the proximity of world4ch to 4chan though, that's not really surprising.

Funny thing though, is that there was an ID system in place there back in 2007 and they didn't even notice it unless someone mentioned it.

On the subject for the most part, I agree with >>2
