I do not know why all of a sudden lately there was no one viewing my articles. It is not that I have so many viewers a day but it seems unusual to get zero views for more than a week now from any of my articles. Before I never fail to have 2 or 3 people reading or maybe just browsing my articles. I would like to think that there was a connection to Google's Panda update.
It looks like you answered your own question by the time you were done writing your post.
I have some articles that get no viewers on a daily basis, but none of them have had no viewers for longer than a week. The only thing I can suggest would be to review what you have written and write more hubs on a different/varied/variety topic. This way, people are not coming just for your 8 hubs, which isn't covering much.
