I am having some doubts while setting up my own network. specifically, the question in my mind is: Will it really work? So far, any seo I have done has been risk free in terms of financial cost. blog comments on high PR, low OBL blogs dont cost anything. GSA posting doesnt cost anything (except the initial fee)....posting articles on wordpress.com and yola.com etc. Doesn't cost anything I have been spending a lot of money on domains and now I am signing up with different hosts. but the financials are starting to break me. I am starting to have doubts. I keep asking myself "will it really work after I spend all this money?" Will it?
