I'm going to cease fiddling with the blog for the next little while and let what I've got sink in before making any additional changes. Even I need some distance from the thing to properly evaluate what works and what doesn't and endlessly tweaking it isn't the way to do that.
As things stand now, though, there are two issues I want/need to fix, above and beyond anything else.
1. The arrangement, size, and hierarchy of the two columns. There's something subtly "off" about the current column layout, not least of which being that one or both might be too big and thus squeezing the post column overly much. If anyone has any practical suggestions on this front, I'd be very appreciative.
2. The Search box brings up a page in the center column but that uses some other element's color scheme, so it's impossible to read. I need to hunt down what element it's emulating and fix that, but if anyone knows offhand which one it is, it'd save me much time.
And this will be the last layout-related post till Thursday at the earliest. My apologies to everyone suffering through this transition. I do appreciate your thoughts and criticisms; I've found many of them very helpful. Given the number of readers the blog has these days, I feel an obligation to make it as legible and esthetically pleasing to as many of you as I can. Thanks so much for helping me along the way to doing just that.
