what's the best way to get content for your web 2.0 sites? scrape sites and spin? outsource it on odesk? fiver? other ideas? also is the content on your tier 1's and tier 2's same niche as your money site? if i want to have 50-100 tier ones each with 20-30 tier twos...it's going to be really hard to have enough content all in the same niche?
