I am building for two of my sites at the same time. I got a silly question: for example I build a hubpage with one of my links in an anchor text. Should I log out when and create another account to build another hubpage? Maybe I should also use proxy? Or is it fine to get both of my links in the same hubpage (or other web 2.0 property) since they are from a similar niche? Thanks for your time and feedbacks.
