I'm sure this has been discussed before. I'm sure it was a robust and vigorous debate.* I just can't find that old thread. Also, there is a new angle to consider.
I'd like to revive whatever discussion occurred about signatures being visible in mobile view.
I'd like to advocate that doing so will further promote SkIP by making PEP Badges visible to the other half of Permies users (i.e. mobile).
*I'm also sure this is a contentious enough topic that I should be donating apples in order to create this thread.
