I think people should paint to their personal best standards. I don't understand people who refuse to paint or who are against painting and prefer to play with unpainted even unassembled models. Why not just use chits or chess pieces then?
As for improving painting, besides collecting links, building the news aggregator, a site for my main army, I did start a dedicated painting blog. There are some tutorials on that site, this one is the most popular. I have a lot of experience painting green having done two ork armies and a Nurgle one.
GW is once again making glazes, they'll probably prove more popular than when GW made them previously due to the Internet and folks properly demonstrating how to use them. I've had mine in my toolbox especially for red and green for years. I'll have to buy the new GW Glazes when I finally get my paints out of storage...
I also am interested in 'triads' particularly I want to try the Foundry Advanced Flesh triad which is actually five stages. I think these sets of three are a good tool for beginning painters as they yield consistent results and is an easy system to follow, but GW is big on washes and drybrushing and not so big anymore for layering for painting entire armies. The Foundry Painting book is a good read, people seem to like the new GW Painting Book and DVD too.
Kids today don't know how good they have it, 145 different shades of paint...
