who knows friday is much more convenient than on the weekends imo.
This is going to be something that varies from person-to-person. I stopped going to FNM regularly because I and most of my friends started working full time 9-5s, and we stopped being able to go out on a random Tuesday Night, so Fridays and Saturday nights were reserved for going out and being with people, and not in a Card store till 10:30 PM. Now, when I play, it's in the Saturday afternoon event, which gives me the morning to do housework, and the whole night to do something else.
When I was in high school, I had a part time job that was noon to 6 on Saturday, so going to Friday Night Magic was actually something that worked for me and was something that I looked forward to.
