What Is The Best Long-Term Stable Strategy?

I would recommend you do all method except Auto Blog,which is not very useful in the aspect of users.But if you wish you want to go with Auto Blog,then use this blog traffic as source of traffic instead of adsense ads for your main blog.

the best long term will be... guess what? your own social network!!! You made a point that Tube got you.
Ok... make your own for your niche! Or make your own facebook.
Why not? i am really thinking about such one right now.
So, if you need joint venture - let me know

in short from me is..traffic...anythign can generate traffic...free content...service...etc...and a bit for you, since you are in adult biz for 10 years, why not make a adult porn tube type site and get your traffic over there and you can mkae a change from there...
