Triond and Infobarrel also offer residual income for freelance writers.
It seems that you've already found the best. I suggest working on those. Trust me, although it's good not to put all your eggs in one basket, you don't want to spread yourself too thin with programs that are sub-par.
All of the above are good places. I make more money from my Squidoo pages than Hubpages. I think this is because on Hubpages the reader actually has to click on an ad on your page to earn money.
On Squidoo, the ad revenue from all 2million+ squidoo pages is split up and paid out to the top 85,000 or so lens pages on squidoo. So if you have a good page on squidoo, you get paid ad revenue even if no one clicks on ads on your particular page. However, if you have an article that has a high CTR you will make more money on Hubpages because you are getting all those clicks.
I find that infobarrel has pretty bad CTRs because of their adsense placements and Squidoo has problems indexing sometimes. Hubpages is pretty much your best bet for making money by writing articles. Fast Indexing, great layout, and an active community, it certainly beats the pants of the other sites!
:3.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
