Blogger is great, but it has its limitations. So I’ve been seriously considering switching over to Ben and Mena Trott’sMovable Type. The more I look at it, the more impressed I am by this grass-roots content management system, especially by the fact that it’s run entirely by a husband-wife team. The wife, Mena, also happens to be a terrific designer, as evidenced by her beautiful personal site, dollarshort.org. All this has me thinking: it’s about time for Subtraction.com to move up to version 6.0.
