Yeah, just from my traffic stats, when people reply or favorite or download most, etc. it seems like more people read on weekdays.

I've found that the fics that get the least responses and looks are ones I post from Friday night to Sunday night.

I'd guess more people browse the fan fiction while they're at work or school, and take off and do other things when they're not tied to a desk on the weekends.

I know if I got another Daily Deviation (and Thank you, Thank you, for that!) I'd want it on a weekday.
