Firstly, what kind of response were you looking for? Is it readership or income?
As in all things there is never an absolute straightforward answer.
If it is readership you crave then you can get that from a number of places:
Hubbers will read your articles if they are aware of them. How do they become aware? By being interested in what you say. This can be achieved by writing in categories that are well supported; making interesting comments on other hubbers articles; participating in discussions on the forums; answering questions; obtaining fans (be aware that your hubscore will be affected negatively if you go out and become a fan of all and sundry to try to obtain reciprocation).
Next you will get readers if your hub is sufficiently well written and optimized such that search engines rank them high enough in their search results pages. This is an art and a science and also a lottery.
If it is money that you crave then all your work gaining interest from hubbers is a waste of time if you only use adsense. Amazon and ebay are a little different. Income is generated from hubs that are successful in the search results game. And picking the right subjects that attract the best paying adsense ads is not an overnight process.
Stay motivated by understanding that time is the factor that increases your readership and income. The longer you stick with it the more chance you have of increases either or both. If you produce regularly and that produce is good and/or effective then both readership and income will increase month on month. You will find you start low and you can become disheartened, but after 6 months or a year or maybe even two years you will understand that consistent effort produces results.
Also remember that there is no rule to say that you have to put all your eggs in one basket. Diversify your output and the ways you monetize. And don't forget that promoting your articles works as long as it is not too overt.
Stick with it - you will be rewarded and those rewards are residual - once produced, the income generated by each hub accrues year on year. Work towards your retirement pension!
