I know qik is one, but that's about all I know for certain. Make sure to use Titanium tobackup any apps you plan on removing beforehand, on the off-chance that removing one that's supposed to be safe causes your phone to misbehave.
Otherwise, I too, am interested. I was planning on comparing a backup of my phone with the apps found on shevrom to find which were safe to remove, but I can only do such a task on the weekend.
