welcome aboard and from me
You can make moneys from all niches and from all these :
"tubesite, image gallery, blog, cam site??" The only one think is do you want ??? If you want you will make.... I am sure
I start some blog sites they not working good (poor traffic) I also try with tgp sites they work fair but not enought for me have some tubes good traffic low ratio (start seling traffic) however Try and you will
I also make more than $500 monthly from gallery submitions many webmasters here will tell you submitions are dead but this is not true
Just try and will see you can make moneys from facebook if you want just must to want , learn and make it
