OK, so, two columns are better than three. Thanks, everyone, for your feedback on and patience with the three-column experiment.
Re: the "4 trillion links" in the blogrolls —
My theory here is that it's easier to keep track of a blogroll than it is to keep track of a bookmarks/favorites file of all the blogs I read, or try to read, or feel like I ought to be reading. So the blogrolls here are mainly for my own use and convenience, although I'm hopeful that others will also find them helpful and convenient.
Some of you mentioned that tucking these ever-longer lists into drop-down menus might make navigating them easier. I like the idea — I just have to figure out how to do that here in the Land of Typepad Templates. (If anybody knows how to swing that, let me know in comments.)
