Hey Nullsleep, yah i know and i´m agree with you. But was that way, mainly to evade purist-haters. I have tons of artists that aren´t in the list that actually are pretty good and has some interesting pieces.
My (just my) criteria was a bit based in the list at wayofthepixels. Which i considerate "the best place to look".. But basically the criteria was a bit like this...
Experience and trajectory (sceners/oldschool artists), good technique (final result of the pieces), unique style (colors and forms), have been an influence to others people or have something that deserves other ppl to see it.
My plan with this list so far, is to make some kind of "BIBLE", so anybody pixel/non-pixel artist can check it and found good information about. And the main plan is to keep it up to date, for some reason the other list are a bit dead, but still have information that arent in this list. So little by little im adding it, reading and checking for new apps, artist, videos, books, etc... im doing it because i like and dig that other ppl can find information about and because there are many things on this list that deserv to be share. So about the artist, i will try to add more and more, little by little. Honestly im waiting more feedback about the list, like yours, because i think this should be made by more ppl than just one (me in this case)
Oh, about the noob, was just a joke, im not really saying that him or me are noobs, is just and old joke. I will probably try to get/ask other pixelartist that are/aren´t in the list and discuss about the artist criteria, because im know is a sensitive point for many ppl (purist/haters).
Sorry for the long msg, is just to clarify "why"
greetings... and also..
UPDATE 
more videos, apps and few words fixed. I still didnt touched the artist part, but defenely im planing to do it.
. The idea is to make this list like a "first aid manual".
and for ppl like me that dont want much information is a bit painful having it. If you guys plan to leave it like that, plz leave an option to switch between the old and the new. Because i personaly dont want all that information
