Questions...and upcoming scans

[flutterbychild.livejournal.com]

What day/time of day do you feel most people respond to posts? I am going to scan a few of my Sketchuary drawings at the end of the month and post them to therebirthofme; people who are interested in seeing more can do so at a price of $2 each. The problem is that my audience isn't particularly active when I tend to post, which is in the evenings and on weekends (I'm in the Eastern time zone).

I'd also like to expand my audience.

Any ideas/suggestions?
