I'm new to Stumbleupon also, my views went way up today but no sales. I have been seeing this is the same trend with everyone else, increased views but no sales. I'm starting to wonder if its worth spending my time on, its already difficult to sit down at the computer and try to market my shop all the while trying to finish up sewing everything I want in my shop by the end of the week. I guess we all will get it figured out someday! Good Luck All!
