I built a linux from scratch a long time ago (before that page existed). You'll learn a lot about how a linux distribution is put together, but that isn't in itself particularly useful. Such knowledge seems most useful if you're working on some hardware device with linux embedded -- where it will be interesting to know about all the parts you can leave off or replace with smaller alternatives.
