I have learned two things in my redesign:
1. Grognardia doesn't belong to me anymore. Enough people read it regularly that pretty much anything I do will be met with dissatisfaction of varying degrees and, frustrating though this fact is for me as I try to find a new look I like, I need to give greater consideration to what readers like.
2. I must be the only person in the world who doesn't have trouble with white text on black background.
So, those two whines out of the way, I'm throwing open the doors to specific, practical suggestions on how to improve the basic look of the site. I'm probably not going to change the layout, because I prefer three columns to two, but I'm open to most other suggestions. I'll only add that I went with a dark color scheme because my current banner is dark and I always found it jarring against the blue scheme I previously used, but if someone can suggest an alternative, I'm open to it. Until I get a new banner -- and that's a whole 'nother can of worms -- I'd like a look that better matches it (though if anyone wants to create a new banner for me, I am not opposed to the possibility).
