this has caused an unintended consequence that is almost self defeating.
Say I want to tether my phone to my wii/ps3/xbox 360. Has anyone actually forum searched or google searched that? all it leads to is a thread on a forum asking the question, which is followed up by "this has been discussed, used the search" Whenever you use the search, you are just led to 1000 threads that say use the search and no real answers.
before the easy root button, I would have dared you to ask "how do you root" because that leads to many of the same such threads.
installing roms/themes/kernals just lead to threads where everyone knows how but explaining how is another issue altogether.
those are the few things I can think of. And I know there are a gazillion "will verizon charge me if I tether" threads out there though
