hey man! been a long time. you raise an interesting point, and i have thought about it, but not very long and with no real conclusion. like even summarizing ryan singer's github nav redesign:

http://ninjasandrobots.com/throwdowns/2

he actually ends up with a couple explorations in there.

or like the new guy at 37s. here's his backback redesign too:

http://jasonzimdars.com/svn/backpack.html

and he's got a couple explorations in there too.

not sure what to do with that yet. not sure if its a do 1-many of after designs? people can now of course just create many new entries with the same before design over and over. obviously not the most efficient. still have to think about this one and see where it goes.
