I already see this. Thuesday revenue is lower than Sunday!
The results on a single site are statistically insignificant. Only Google can tell us if AdSense itself took a downward turn due to a government furlough. FWIW, I find Thur-Sat has become my off days when it used to be Sat-Sun so I couldn't say.
Maybe I incorrectly assumed that workers with a few days off might be online doing a little shopping in their spare time and give AdSense a bump.
If in fact AdSense goes down instead of up during the government shutdown, then we know those workers weren't really working in the first place and probably deserve to be furloughed.
I think certain internet sectors related to entertainment, employment and possibly apparel/home might see a bump.
