Well I use all three, but I find I make the most money off Infobarrel. Even though Infobarrel's Alexa ranking is a bit lower, it still seems to rank as well if not better than the other two. Just a few things to consider.
I have not tried using squidoo but have used both hubpages and infobarrel. I like the design of hubpages the most.
I like the design of Hubpages the best. It's very easy to add new modules. I've made some very similar pages (same topic, similar titles) on both Hubpages and Squidoo, and hubpages gets WAY MORE TRAFFIC than my squidoo pages.
BUT, on pages where they are buying pages like product reviews or something, I've had MORE SALES on my Squidoo pages. I've just started using Infobarrel, so I can't really compare them.
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.
A religion that was able to fool over a billion people. Create fools of people who believe they can reach heaven by following ancient traditions set forth by a madman named Mohammad. Islam is a cancer on this world and the only way Muslims can save themselves is to wake up from the daydream that has enslaved their minds.
