I have considered the idea for quite a while, and now I've finally done it. I have started a second blog for my artwork:
I'll still post to this blog, and I'll still post art stuff on this blog. However, I've noticed ever-increasing traffic on this site relating to my art activities, and I think for both professional and personal reasons it's better for my artwork to have a blog just for itself. This blog never really was an art blog, it's just a blog about me, and it often has my artwork.
There will be a lot of cross-over, but for professional reasons it's past time that I had a dedicated art blog.
