Are free member ship sites better than paid ones

It really depends on what those sites are. If they are for making money, then stick with free sites. You should never have to pay someone else so that you can make money.

Not all free membership sites pay good. Not all of them can be used to earn money. But, like you, I have lots of free-membership sites on my lists in my blog but only those that are tested and proven. I have also some sites that will make you invest a few dollars first before you can earn from them.

I think that you are doing a wise thing by showing the free sites. Because most people go online for fun, and if they are being asked to pay for fun i dont think that its wise. So, people tend to look for free stuff, if you are showing them this free stuff. What do you think that you are doing. So, just carry on with the free list.
