Big data wonks and social scientists/observers all: if you want a pic to get noticed because you put some time and thought (or risk) into it, what time of day should you post it? My pet theory has always been between 60 and 90 minutes into the average workday. But bedtime might be best.
About 10.30pm, after 11pm everyone is getting into bed. I always get in influx of messages if I'm still online. Would imagine it would even more of I posted new pics.
