Submitted for the ONE Waterloo Diversity Contest:
At UW, every student has their personal preferences and attitudes. These are what makes up individual personalities. UW students are diverse. If you ask any class of students about their favourite operating system, you would get as many different answers as you would if you asked them about their favourite food. The same goes for favourite editors. Diversity is UW.
Despite the fact that no one uses 3p1c_ph41l_d0w5, I decided to include it in the photo for the sake of brevity. Note that I wrote the above paragraph very neutrally. Please keep the comments clean. No religious wars about favourite operating systems or favourite editors.
