I hate phone calls, so I believe in a telephone armistice. To me, the idea of calling someone unprompted is basically saying, 'Hey, stop whatever you're doing and talk to me right now.' If you find yourself in the middle of something, getting an unprompted annoyance is incredibly frustrating.
I am consistently impressed by reddit. I'd say on a near weekly basis, by little things. Whether it's - I absolutely love seeing the Photoshop jobs that people do. Not of silly cats, but of redditors who are like, 'I have this photo of like my mom. This is the last photo I took with her. She was in the hospital. Can any of you clean this photo up?'
