For the most part, so can I, but faceless masses, etc..etc...
I have a rigorous categorization system. Faceless internet identities are categorized by website, then by first impression, then by encounters.
So Faceless Internet Identity (FII) RMRK (RK) 29-34 would refer to the 29th RMRK profile that I saw a post of, and I have seen him post 34 times. Once the third number reaches 150 I will memorize their username. Otherwise, I might memorize their username if they've made a good impression on me.
So, that Alphonse guy is like FII RK-274-98. It makes knowing who people are much easier with such a simple and coherent system of categorization. It's even better than the Dewey Decimal System.
