Magnachrom was POD right? I liked it.
I also see real value in a POD journal that at least strives to pull some wonderful pieces from the torrent of content that runs by us all too quickly. I refer not only to images but also beautiful comments or insights (all of which could be nominated per my hypothetical button, ahem).
The great thing about an internet forum like this is that it delivers so much content. But that is the bad thing too, of course... so much fine work gets buried. A journal might at least elevate some representative items from the blur.
And there is a pride aspect too, let's be honest. Some apuggers would be really tickled to have an image in a journal or book. I like that thought. Let this cultivate the egos of those people, rather than those of any single editor.
