I use the same site for several things, including my game maker (I couldn't find stable hosting for it anywhere else).
Honestly I think the site is coming into its own as a starting point for learning. Now honestly PixelJoint would probably be a better home for this kind of project. I notice that the materials there are very good, and I'm linking to several of them from the wiki. But I hope people understand that neatly organized information has value. Search is good for getting the latest information about something you have basic familiarity with, but the world's internet forums are no match for Wikipedia when it comes to gaining intellectual foothold.
If I see something like this happen at PixelJoint, I will probably take the wiki down. I am also open to handing the wiki's backup over to PixelJoint proper, if they want to host it. At the very least, I think WikiPixels is a good name and that its logo should be preserved, because it was very gracious of its author to make it.

I am adamant that extensive, well organized reference material is key to the usefulness of a wiki such as this. Putting all the palettes you can find on one page, or even giving them separate articles, is not a bad thing. But one thing the wiki should not be subject to is immature trolls. I've seen them in action on other wikis for other topics, and they literally strangle their evolution. It's controversial to ban them but I think it's for the best.
In some ways the wiki is treated like my personal resource but it's simply not my nature to stockpile private information. If I'm going to exert my mental activity in novel directions, then I want it to be of use to others. I understand their needs may differ and I'm willing to negotiate to the extent that the resource in question continues to serve my own intellectual need. Although I can be gracious I am no altruist.
I do want people to participate, so long as they respect my contributions. In general I think contributed information represents well-intentioned mental effort which should be respected.
