I'll have to look around and see if I can find that old site.
I do remember DA had some really great tutorials, and Pixeljoint was full of neat stuff to look at. Twitter was also a good place to check sometimes.
In a bit less mature vein, here's a 2D pixel sketch I made a while back that came to mind. I was trying to recreate the enthusiasm I had when drawing combat pictures as a kid.
When I taught art at the local college, I would sometimes give extra credit to students who tried pixel art, and I usually spent some time demonstrating how photoshopping could be done effectively and even quickly at the pixel level.
If you can work effectively with pixels (and maybe beziers in the vector world, not just the manipulation technique but the minimal-node style), you can pick up just about any graphics tool faster. I would even include 3D design tools in that.
I thought it was pretty exciting at the time, but it was actually amazing how few people really got it.
Celebrating pixels and pixel art only seemed to make sense to a small group within the overall population, even of portfolio-reviewing folks.
This came as a minor shock to me, as someone who was surfing Pouet and various pixel art sites all the time. :-)
