I visit the Kindle forum less then I used to (and less then the forums for some of my older devices) partly because of the clutter and chaos.
You just brought up an excellent point. One cannot search for K1, K2, K3, KK, KT or K4. That just doesn't work. So prefixes would allow searching for threads about the different Kindles since searching does not work. So because of this, it's impossible to do a search that finds all the threads you are looking for.
