I always shave after my shower, no matter the time of day. Most weekdays that's in the morning. On weekends it depends on my social activities. I used to shave before, but I now agree with the premise that a beard is easier to shave after being moisturized in the shower. I haven't tired during, but I think that would be too much trouble with a brush, bowl and razor and multiple passes. It would also be waste of water. I think part of the enjoyment of shaving is just taking your time at the sink.
