Neat idea. My strategy has been to minimize the amount of shared headers and footers. Your method seems much more flexible.
Took a look at your blog—it’s sweet! I will be sure to include it in my next href hunt. I enjoyed the article about Dat and am interested in finding others who write about practical uses of the ‘dweb’—unfortunately, many of the links on Tara Vancil’s directory are ‘broken’ (perhaps ‘vanished’ is more correct?) and I’m not sure how to discover more.
At any rate, good to meet you!
