+Why did you write all of Django from scratch, instead of using other Python libraries?
+--------------------------------------------------------------------------------------
+
+When Django was originally written a couple of years ago, Adrian and Simon
+spent quite a bit of time exploring the various Python Web frameworks
+available.
+
+In our opinion, none of them were completely up to snuff.
+
+We're picky. You might even call us perfectionists. (With deadlines.)
+
+Over time, we stumbled across open-source libraries that did things we'd
+already implemented. It was reassuring to see other people solving similar
+problems in similar ways, but it was too late to integrate outside code: We'd
+already written, tested and implemented our own framework bits in several
+production settings -- and our own code met our needs delightfully.

 Do you have any of those nifty "screencast" things?
