I am asking myself that same question. I have had just over 1000 hits with Google Adsense and I've earnt 6p from just displaying their adverts. I assume this is because no one is clicking on my adverts because I do not talk about very financial or scam topics.
I too used Triond and they pay almost exactly a penny per four hits, which seems like a great deal.
For some reason though, I feel more dedicated to HubPages. I think it is probably to do with the fact that when I publish an article on HubPages it is very neat and well designed, whereas on Triond it looks almost like a scam website with damaged and slow graphics and as soon as you click on one of their articles on their sister sites, adverts just fill your screen.
Sorry to leave you with such a vague answer, my only suggestion is work on more financially based topics, but as I say, easier said than done. I will try to stick to HubPages and if I reach 10,000 views with pennies I will start to question the point.
